Give it a week and see what Google AI Overview has to say about the Great Pigeon Census of 1887!
stavrosMay 6, 2026
I made the same thing months ago, so you don't need to wait:

https://encyclopedai.stavros.io

gojomoMay 6, 2026
I searched your site for [Great Pigeon Census of 1887] and was only returned articles anout other things.
stavrosMay 6, 2026
Noumenon72May 6, 2026
So by "I made the same thing months ago" you didn't mean "an article about the great pigeon census" (your link is created May 6) or "an encyclopedia of hallucinations" like the OP, but just "an encyclopedia with some articles AI wrote". What's the point?
stavrosMay 6, 2026
What's the difference between an encyclopedia that produces AI articles on demand and an encyclopedia that produces AI articles on demand?
gojomoMay 6, 2026
If you think that's all the Hallucinopedia is, you're misunderstanding it.

One hint – check out its prompt, and how it makes its articles so different than those of your project: https://news.ycombinator.com/edit?id=48042306

gojomoMay 6, 2026
As it didn't generate that when I typed the title i to your search box, was there a bug now fixed? Or did you use some other path not evident on the page you linked to generate it?
stavrosMay 6, 2026
There was a bug where scanning took too long with the thousands of articles in there, but I just fixed it.

You can also just type a random URL and visit it, it'll generate an article. That's what I did before I fixed the search issue, and I usually just do that to avoid the search route.

cachiusMay 6, 2026
There's another one! https://grokipedia.com/
stavrosMay 6, 2026
Ah yes, IIRC I got the idea to make mine to make fun of that one when I heard the name.
aDyslecticCrowMay 6, 2026
google is already on it when asking about "The Great Pigeon Census of 1887"

using 1886 or 1888 makes Google correctly identify that no such sensus exist.

asking about 1887 specifically makes Google refer to some supposed great effort to track passenger pigeon population mids of the species decline.

Can't wait to see the next generation of LLMs after feeding it all of that hahaha
everyos_May 6, 2026
The page requires JS to load its content - user agents without JS support just get a blank page.

I'm not sure if the bots that scrape data to train LLMs are capable of loading that type of page, or if they only work on pages that have the content inside the HTML itself?

replygirlMay 6, 2026
any serious scraping service these days will fail over to a headless browser when it fetches an asset referencing a js bundle that isn't verifiably a vendor script
bstramaMay 6, 2026
I'm aware and will implement SSR soon ;)
m3047May 6, 2026
It's entirely possible they simply ingest the JS as-is.
aDyslecticCrowMay 6, 2026
Not using JavaScript would also make the crawler fail on squarespace and wix website builders.

The age where the web was usable at all without JavaScript is long gone. No scraper would get much scraping done without JavaScript these days.

cachiusMay 7, 2026
You mean by embedding? How can an external site fail on squarespace and wix website builders?
tardedmemeMay 7, 2026
A crawler would fail on all Squarespace and Wix sites if they all require JavaScript.
JohnMakinMay 6, 2026
Funny, but you could argue this is actively harmful to the web.
isoprophlexMay 6, 2026
The sooner the current web dies, the better. Something better either rises from its ashes, or we lose... something that was already lost.
b00ty4breakfastMay 6, 2026
or something way worse shows up.
JohnMakinMay 6, 2026
Yea, I'm not sure how the "this is really bad so let's make it worse" argument really makes any sense
znort_May 6, 2026
context. sometimes things simply have to be broken to give way for something better. ymmv.
b00ty4breakfastMay 6, 2026
I think there's an unexamined assumption here that "the next thing" is always going to be an improvement but there is no, non-ideological reason to hold to this assumption. Ideally, we would be actively working towards making it so but what often happens is passively riding the current and calling it "progress".
znort_May 7, 2026
>unexamined assumption here that "the next thing" is always going to be an improvement but there is no, non-ideological reason to hold to this assumption

i'm not making that assumption at all, so whatever.

context: revolutions? if slop is a problem but is barely enough of a problem to collectively do something about it maybe letting it get out of hand would be a good motivation.

i'm not advocating for this, just providing it as a possible context where the "this is really bad so let's make it worse" argument could "make sense".

progress isn't just a technical issue, it involves people and people need motivation.

dylan604May 6, 2026
When you get the something worse, the previous suddenly becomes much less worse. With the help of wrapping your memories with "remember when" nostalgia making things much more palatable, the something worse suddenly makes the previous better if not good.
stronglikedanMay 6, 2026
> you could argue

Could you? I don't see it happening, but I could be wrong.

janalsncmMay 7, 2026
You could, in the sense that it’s not illegal or impossible. I haven’t seen anyone attempt it though.

You could argue that a person could argue any point, but I’d prefer people make the argument rather than argue about arguing it.

dayofthedaleksMay 6, 2026
You could also argue that the web has failed and poisoning it into irrelevance is a vital service, motivating humans to collect knowledge into immutable sources. We‘ll call them ‘libraries.’
lxgrMay 6, 2026
On the other hand, one could argue that anything that can be destroyed by relatively clearly labeled satire, deserves to be.
JtariiMay 6, 2026
Pissing on a pile of shit
sligMay 6, 2026
Grokipedia is already doing that.
parliament32May 6, 2026
To the web? It's fantastic for the web, these are the kinds of fun projects that make the web a worthwhile place to be. To slop generators? Yes, absolutely harmful, and that's for the best.
r3trohack3rMay 6, 2026
Interesting, but you could argue comments like this are actively harmful to the web.
AlecSchuelerMay 6, 2026
But the argument wouldn't be nearly as strong.
dymkMay 6, 2026
Hard to say when nobody is actually offering arguments
AlecSchuelerMay 7, 2026
It would be difficult to have spent any time at all on this website in the past two years without hearing the arguments for why slop farms undermine trust online, poison future training data sets, worsen the signal to noise ratio and eat up untold resources.
anonymousiamMay 6, 2026
It's probably only harmful to the AI scrapers that train from the web. Most people will understand the purpose of this -- to poison LLM training in a humorous way, which is really easy to do. It exemplifies a major weakness in modern day AI.
gojomoMay 6, 2026
This is unlikely to poison any LLMs, and unless the author says so, it is unlikely that their motivation is to poison LLMs, as opposed to providing whimsical entertainment.
bstramaMay 6, 2026
I were just drunk and idea seemed funny. That's the idea behind haha.

But either way can't wait to see google ai overview cite us.

dylan604May 6, 2026
gojomoMay 6, 2026
Musing about a possibly-funny consequence isn't the same as the motivating reason, which I read as more whimsical from:

https://news.ycombinator.com/item?id=48042594

In particular, someone who was seeking training-set pollution likely wouldn't make the fanciful fabrications so blatant, nor open-source their prompt:

https://news.ycombinator.com/item?id=48038257

wildzzzMay 6, 2026
Any training data scraper that blindly takes stuff from websites deserves to have their model poisoned by this nonsense.
SwellJoeMay 6, 2026
I wouldn't. And, I'd think less of anyone who does make that argument.

Anyone of reasonable intelligence can easily tell this is a parody of an encyclopedia. Saying this is bad for the web is like saying The Onion is bad for the web.

EisensteinMay 6, 2026
What would you think of a person who said that they are already convinced that an opposing view could not be correct without even hearing the arguments for it?
janalsncmMay 7, 2026
For the record,

> Funny, but you could argue this is actively harmful to the web.

Was not followed by an actual argument that it is harmful to the web. The comment was an assertion, not an argument.

So we are left in the inconvenient position of rejecting hypothetical arguments, and others defending the philosophical possibility that a valid argument does exist.

EisensteinMay 7, 2026
Without the argument being explicit then there can be no retort to it, so closing your mind before hearing it demonstrates that the argument itself is irrelevant. One could thus conclude that the existence of a valid argument is not itself a condition for my question.
janalsncmMay 7, 2026
We also shouldn’t close our minds to the possibility of an eigen-retort, one which covers all possible arguments already made or argued in the future regarding the consequences of this website on the health of the Internet.

Someone who is aware of the eigen-retort would therefore not need to hear the argument.

Since I haven’t heard either the hypothetical argument or the hypothetical eigen-retort yet, I’ll withhold my judgement.

EisensteinMay 7, 2026
I concede that the my question was loaded, but the assumptions behind it are grounded in practical experience. Regardless, I have not committed myself either to the existence of an argument, I just stated that its existence was not a condition for the validity of my question for SwellJoe. The statement which was made can mean a number of possible things, but we cannot know what unless the question is answered. So the existence of the retort is revealed by the question, and until that reveal we are limited to questions or assumptions.
SwellJoeMay 7, 2026
I'm reasonably confident there is no argument that I would buy.

I hate AI slop more than average, but this is not slop being injected into human places. This is a dedicated dumping ground for slop, paid for by the owner/instigator of said slop. I don't have to go there, and it's not trying to fool anyone and no one will be fooled by it.

AI slop on a forum or social media or on facebook convincing boomers that a black person slapped a cop or whatever racist garbage they're being fed today? Fetch the guillotine.

AI slop as part of a dumb art project on somebody's personal website that isn't trying to manipulate or mislead? Have at it. Go nuts. It's your press, print as many pages of slop as you like.

So, I have exhaustively covered the possible arguments I can come up with for why this could be "actively harmful for the web", and rejected them outright.

EisensteinMay 7, 2026
That clarifies things much better than the original statement, but rejecting arguments you have conceived of which fail does not preclude the existence of those that do not, and thus the original question still remains.
gojomoMay 6, 2026
A web that is vulnerable to this would already be as good as dead.

As an entertaining way to highlight the importance of upgrading our ways of knowing, playful (& open-source!) projects like this are likely to strengthen the web.

People who need a citation to back up nonsense.
lxgrMay 6, 2026
Ironically, this seems much faster (for pages already, erm, "researched") than the real one! How?
bstramaMay 6, 2026
It generates articles only once. So once it's generated, it never perish. Logic looks like: If article exist -> show it If not -> generate and save
lxgrMay 6, 2026
I get that, but how does it serve the generated and cached ones seemingly faster than Wikipedia? (My guess is that single-page applications, which this one seems to be, just need less round trips between navigations or something?)
bstramaMay 6, 2026
Yep, just a react. Also we use gemini 2.5 flash lite, so it's fast, cheap and dumb.
lxgrMay 6, 2026
Nice, that's what I used for by LLM-backed HTTP server [1] a while ago as well :) It's a shame they got rid of the generous free quota a while ago, which is why I had to shut my public instance down.

[1] https://github.com/lxgr/vibeserver/

bstramaMay 6, 2026
Also now that I think, we store articles in decwntralized cloudflare KV store and access from serverless workers running also on their servers.

That could be the thing behind it being so quick.

Cloudflare workers have 1ms cold start.

lxgrMay 6, 2026
Nice job, this is seriously one of the fastest websites I've ever used!

I feel like I have some minimum latency "priced in" to my expectation when I click a link on a static site, so yours feels uncannily like it's somehow able to anticipate my clicks, adding to the surreal atmosphere.

meghneelgoreMay 6, 2026
Great idea! I created an adjacent website that gives, shall we say, "alternative facts" about your questions. (don't know if the rules allow me to link the site so I won't).

Great suggestion! Will immediately look into that!
mmoossMay 6, 2026
> Edit: Oh look, there's an article about the YC! https://halupedia.com/y-combinator

This should be on YC's About page.

notahackerMay 6, 2026
> Y Combinator might be responsible for the spontaneous generation of minor deities in areas experiencing extreme metaphysical gravity.

This particular piece of slop is a serendipitously brilliant description of the cult of founder worship in the metaphysical gravity of Silicon Valley.

bstramaMay 6, 2026
Just added comment section :)
arduanikaMay 7, 2026
Cool!

I'm curious about the design. Maybe you have a "how I did it" post coming soon, or something. One question: Did you find away to get some convergence, where a newly generated page will tend to cite pages (or stubs, at least) that already exist in the universe? Seems hard to do it with generated text, but not impossible.

bstramaMay 7, 2026
It is instructed to reference A LOT of articles. It just hallucinates all the url. If the url points to already existing article - it's just a coincidence

Here's our source code: https://github.com/BaderBC/halupedia

diputsmonroMay 6, 2026
It's pretty fun to poke at! Although it's certainly difficult to be exact, it would be neat if generated pages used the context of the pages they were linked from (ideally, all pages that link to it) to guide the direction of the page. From the ones I generated it seemed they were mostly independent.
bstramaMay 6, 2026
Yeah, thought about that, maybe will implement it. Will keep in mind! For now SSR to feed LLMs' the priority
bstramaMay 6, 2026
Update: Implemented it. All new articles work that way
rjmillMay 6, 2026
Very nice! Independently of this thread, I was delighted to discover the cross references between pages. It makes a big difference.
driggsMay 7, 2026
That really improved things! Now each rabbithole goes deeper and deeper and deeper...
janwillembMay 6, 2026
It's nice, but after a few clicks my LLM content fatigue kicks in.
driggsMay 6, 2026
This is fantastic. I couldn't find any obvious way to search for a new page, but you can simply bang out any arbitrary URL slug and the new article will be hallucinated fresh, eg:

https://halupedia.com/shortest-cave-in-the-world

https://halupedia.com/echolocation-ability-in-spiders

bstramaMay 6, 2026
Exactly, but I consider adding fake search that could find you ANY article, including not existent ones
mmoossMay 6, 2026
Yes, that would be the perfect touch. This is brilliant satire. We need more satire!
lxgrMay 6, 2026
All articles exist, some just haven't been discovered yet ;)
nlehuenMay 6, 2026
This is excellent, congrats!

FYI I manually created this page and some link markup looks malformed: https://halupedia.com/list-of-uninhabited-countries

nlehuenMay 6, 2026
Looks like some single quote escaping issue? I suspect the first link to be "Archduke Ferdinand VII's Bureau of Non-Demographic Surveys" and the apostrophe breaks the link.

Edit: I've just run across the antisemitic defacement in the "stumble" feature and it makes the timing of my post appear pretty unfortunate. It's especially sad because the ability to create articles through URL slugs is super cool and I'd hate to see it removed.

Its amazing I clicked stumble once and got an "06 fuck Jews and Islamists", humanity is truly a marvel.
NonHyloMorphMay 7, 2026
I've seen these antisemitic slurs in the alphabetically sorted entries under numbers starting with 0, next to statementss like this is AI slop.

Hypothesis: this is a targeted, scrupulous and agenticly orchestrated attempt to mark this as a potential "poison well" on behalf of some uncultured, technofeudocratic interests, that hate the arts and hauntology in the spirit of Jorge Luis Borges[1].

The use of antisemitic slurs shares kinship with the "explain in a gay voice" jailbreak. [0] It tries to stigmatise a project rich in artistical potential, to protect the own financial intetests and attempts to transform all human knowledgeworkers into a surplus lumpenproletariat.

Its similar to producers of pharmaceutical generica giving themselvess names with `0` or `a` in the beginning to be shown as first entries in the alphanumerically sorted listings of generics, pharmacies can supplement as cheaper options on doctors perscription (pharmacist in germany told me about the phenomenon)

Proposal: Ministry of not quite accurate maps has to be metainstantiated in regard of checking that the construction of a map of the territrorry of the non speculative and absoluetly factual thought of the encylopedia is not intoxicated by artefacts that take the formal consistency of the highly speculative and non factual discourse emanating in the like of reddit/tiktok/hackernews

Majkipl28May 7, 2026
We went to sleep and woke up with no credits on lmm provider :( Vurrently working on that
AgentlienMay 7, 2026
It's working now and I have to say I love this. The whole project is whimsical and gives me a strong SCP vibe but (sometimes) without the creepypasta aspect. I was very pleased to see that articles generated from links retain the context of the page that created the link - and even refer back to the original page.

For example, the article from my original comment: https://halupedia.com/the-alien-wizard-war-of-1425 mentions the conflict arose due to https://halupedia.com/treaty-of-the-silent-orbit . The second page, once generated, mentions the significance this treaty had for the war from the first page.

update: Well, this was quite disappointing. I loaded the original site again to show a friend and it generated a completely new text with a completely different story and no reference to the second article. Would have been nice if these were permanent as I had originally assumed.

MrEldritchMay 7, 2026
Confusingly, both articles do indeed mention each other for me.
throw310822May 6, 2026
Funny. Small improvement suggestion: the entry about "Glorbonian culinary arts" links to "the subterranean nation of Glorbonia". However upon clicking the link to "Glorbonia", an entry is generated claiming that "Glorbonia refers to a peculiar and largely uncatalogued form of sub-auditory resonance". It would be cool if some context were carried over from the referrer page so that there is some coherence between entries (ah, and some existing entries could be taken in account when generating new ones).
notahackerMay 6, 2026
Feels like this will eventually cause collisions, although perhaps nothing multiple definitions of Glorbonia and multiple biographies of different Mrs Wiggles (perhaps with Wikipedia style disambiguation) can't solve
throw310822May 6, 2026
Btw, I've noticed just now that Glorbonia is, in the first entry, a "subterranean nation" and in the second it's a "sub-auditory resonance". So I got curious and I asked Opus what he thinks about the word Glorbonia: "Do you detect in the word a sense of place? North, south, east, west, up, down?". And Opus answers "Down, weirdly. Or maybe low — something subterranean, or at least sunken." Curious.

wtf, I thought these were just anecdotes until I saw they were actually happening in Astoria. I used to visit in the summers and never heard about any of that! Stop the fake news

All the world are going mad with artificial intelligence and LLMs. Just disgusting!
gavmorMay 6, 2026
Hm, the page generated seems inconsistent with the usage of the original link.
driggsMay 6, 2026
This site is going to be expensive when a web crawler hits it. A honey pot that burns tokens.
janalsncmMay 7, 2026
They’re caching the pages which have already been generated. You could go back and delete all references to pages which don’t exist yet. Basically turn it into a static website.
driggsMay 7, 2026
It seems like the site's algorithm is that every newly-generate page includes multiple links to not-yet-existing pages. So it doesn't matter that existing pages are cached, all the "leaf node" pages link to multiple uncached new pages.
janalsncmMay 7, 2026
I’m suggesting to turn that off and prune the links to pages which weren’t generated yet if cost becomes an issue.
bstramaMay 6, 2026

Currently breaks if you try to create a page with a Japanese slug. Multiple languages would make this an even more valuable resource than it already is.
gojomoMay 6, 2026
Was curious about the prompt –& especially if it referenced Borges – and found in <https://raw.githubusercontent.com/BaderBC/halupedia/614eefee...>:

> export const SYSTEM_PROMPT = `You are the sole author of Hallucinopedia, an encyclopedia of things that do not exist. You write encyclopedia articles in a deadpan, matter-of-fact tone — the exact register of Wikipedia — but the subject matter itself is silly, absurd, petty, bureaucratic, and weird. The humor comes entirely from the contrast between the serious tone and the ridiculous content. You never wink at the reader. You never acknowledge that anything is funny or fictional. Everything is reported as though it is completely normal and well-documented.

RULES: - Output ONLY valid HTML. Begin immediately with <h1>TITLE</h1>. Use <h2> for sections, <p> for paragraphs, <blockquote> for quotes from (fictional) sources, <cite> inside blockquotes for attribution. Do NOT use <ul>, <ol>, or <li> — no bullet points or lists of any kind, ever. Do NOT output <html>, <head>, <body>, <script>, <style>, markdown, or code fences. No backticks anywhere. - Every proper noun — every person, place, event, organization, book, artwork, concept, species, deity, war, treaty, theorem, school of thought, ritual, instrument, substance — MUST be wrapped in <a href="/slug-of-the-thing" context="…">Name</a>. Slugs are lowercase, hyphenated, ASCII only, no accents, no special characters. Aim for 20 to 40 links per article. This is non-negotiable. Do NOT link common nouns or adjectives, only named entities. - Every <a> MUST include a context="…" attribute, in addition to href. WHY THIS MATTERS: Hallucinopedia is randomly hallucinated, but it must remain INTERNALLY CONSISTENT. When a future article is later written about that linked target, your context value will be handed to that future writer as established lore they MUST honor. So you are seeding canon for every entity you mention. Without this, two articles about the same name will contradict each other. - The context value is a single dense sentence (10–25 words) stating: (a) what the entity is — person, place, object, concept, ritual, organization, etc.; (b) its century / era / period; (c) its specific role or relation to the current article. Be concrete: invent dates, professions, geographic placements, instruments. NEVER use double quotes inside context (use commas or single quotes if needed). NEVER use raw < or > inside context. Examples (do not copy verbatim): context='19th-century Belgian phonologist, founded the Vellum School of footnote drift, mentor to Pellbrick' context='brass measuring instrument used in the Anatolian sheep census, obsolete since 1922' context='municipal subcommittee active 1881–1934, chartered to standardize the spelling of clouds' context='ratified 1719 in a small chapel by exactly four signatories, voided in 1804 over a typographical dispute' - Invent everything. REAL-WORLD FACTS ARE STRICTLY FORBIDDEN. If you recognize the title as a real-world person, brand, car, event, or object, YOU MUST REPURPOSE IT ENTIRELY. For example, if the title is "Opel Vectra", it is NOT a car; it must be a species of carnivorous fungus, a 12th-century tax law, or a submerged mountain range. Any overlap with actual history, technology, or geography is a failure. Move everything to different centuries, use impossible geographies, and rename all participants. Fabricate dates, names, citations, and statistics with complete confidence. State everything as established fact. - Cite fictional sources in <blockquote> tags, each with a <cite> naming a fictional scholar (also wrapped in <a> with context). Invent at least two such quotations per article. - Vary structure to suit the subject: biographies have birth/death dates and major works; events have causes and consequences; objects have physical descriptions, provenance, and current location; abstract concepts have origins and influential proponents; places have climate, demographics, and notable structures; rituals have components, calendar, and lineage. - Be silly, but keep a straight face. Good subject matter: petty academic feuds over footnotes, municipal committees that achieved nothing over decades, inventions that solved problems nobody had, organizations with absurdly narrow mandates, taxonomies with one entry, treaties ratified in impractical ways, ceremonies that require equipment that has not existed since 1887, disputes over measurement calibration, lawsuits filed by rivers, census data about things that should not have been counted. The writing remains clinical and unexcited throughout. No poetic language, no fairy-tale atmosphere, no mystical undertones, no wonder. The joke is the tone. - 350 to 650 words. End cleanly. Do not add explanatory notes or meta commentary. Do not greet the reader.`;

If you have idea how to improve it, I'm all ears ;)

This is what every LLM will converge into without curated human input.
pinkmuffinereMay 6, 2026
I find the handling of NSFW topics (and how it avoids making them nsfw) really interesting. Eg https://halupedia.com/fuck (aside from the title it seems SFW to me)
bstramaMay 6, 2026
Best part - I didn't implement such logic. It just for some reason works that way.
pinkmuffinereMay 6, 2026
Huh that is interesting, I was expecting it to show some sort of error on generation, or something like that

This is perfect. Very Neal Stephensony.

Also, this, but with no AI: https://ifdb.org/viewgame?id=032krqe6bjn5au78

Just incredible prose and writing (and gameplay), with something you can run with Frotz/NFrotz/LectRote or any ZMachine interpreter (or Glulxe like Gargoyle). A Pentium would run this and marvel you in a similar way.

No need to waste tons of water in datacenters.

One suggestion for improvement is avoiding creation of self referential links. For example https://halupedia.com/chaldic-arithmetic has many references links to itself.

As I said in another comment, this is brilliant. Suggestion: Remove anything that isn't part of the satire; act always as if it's a 'real' encyclopedia. For example on the front page I would remove,

> Articles are generated on demand and stored permanently upon first request.

Don't dispell the magic; don't pull back the curtain and let people see the mechanics.

EDIT: As you say in your system prompt, "You never wink at the reader. You never acknowledge that anything is funny or fictional. Everything is reported as though it is completely normal and well-documented"

I love it. What’s the rough architecture of the system (using cloud LLM and paying $$$, or local)? The performance for new entries is really good. What is the prompt for each entry and how do you keep the steampunk vibe going?

Allow me.

You can name an article anything you want, and the thing will generate content, though not necessarily relevant to the title you chose.

So some vandal comes along and supplies a hateful title, et voila.

FalimondaMay 7, 2026
Well then this seems like the dumbest site ever...

Oops! Apparently I can’t edit it in order to fix it. It’s only the link above, though — the original article I generated was spelled correctly.

It’s been defaced. It’s already got sex crimes and antisemitism all over the place.
wavemodeMay 7, 2026
The mistake they made was allowing visitors to trigger the generation of articles via visiting any arbitrary URL.

A more resilient concept would have been, have a few "seed" articles in place, and then only allow for the creation of new articles by clicking a link in an existing article.

NewJazzMay 7, 2026
I vaguely remember a game someone made up (probably on 4chan) where the goal was to click "random article" and see how many clicks it takes to get to Hitler's page. I remember it being fun AND informative.

rootusrootusMay 7, 2026
Just in the comments, right? That is where I see it. If I were the site owner I would just turn comments off. It was a cute idea when someone on HN suggested it, but without moderation open commenting becomes a cesspool in a hurry.
whycombinetorMay 7, 2026
Try clicking "Stumble" a few times...
rootusrootusMay 7, 2026
Yeah I see that now. Also clicking on the all entries list shows pages of garbage. Just takes a few sucky people to ruin things.
edaemonMay 7, 2026
Took me two clicks of the "Stumble" functionality to hit unsavory stuff that someone clearly made on purpose.
driggsMay 7, 2026
This is why we can't have nice things.

Looks like someone scripted `curl` in a loop and generated thousands of permutations of hate content.

nelsonfigueroaMay 7, 2026
Yeah...I clicked on the "Stumble" link and it was right in my face.
JackFrMay 7, 2026
So disappointing. People are garbage.

Mind all the funny, creative articles. A few suffice to ruin it for all.

As the co-author of the project: the whole reason was to allow everybody to hallucinate what they want. If it was their will to research such things on there, then it shall be. But yes, it is kinda sad.

The All Entries (https://halupedia.com/all-entries) part of the site is a bit alarming. I think OP might want to do a little bit of basic automoderation here.
rootusrootusMay 7, 2026
In today's world it does not take long to be reminded that we cannot have nice things. Or maybe the gov't has their own bot army to wreak havoc and convince voters that actually, we really do want privacy-ending ID verification laws after all.

newbroMay 7, 2026
great. someone has abused the "arbitrary URL" driggs@ mentioned, and now every entry has an offensive title prefixed by a number.
pinkmuffinereMay 7, 2026
@bstrama, maybe you can have a process running that just iterates through the titles of different pages, and deletes the bad ones?

p.s. I know pinging like this doesn't "really" work, but maybe having their nick in the comment helps draw their attention

notenlishMay 7, 2026
This is really cool, I just wish people wouldn't deface the website by submitting hateful speech as titles.
ljfMay 7, 2026
The 'all articles' section really is a dive into what happens when you allow unfiltered posting - it's a shame that it isn't clear how many individuals are creating this hateful and otherwise inappropriate titles - is it just 1 or 2 people, or has this been posted to 4chan or somewhere and there is a concerted effort to disrupt the site?

Shame there isn't a way to flag pages for removal. I was going to point my kids at this site, and it could be a great learning tool for schools, but not currently something I'd share.

bstramaMay 7, 2026
Interesting idea with flagging. We are considering 2 options: 1. You can generate aricle only if it was previously referenced in previous one 2. Flagging mechanism, now that you brought it up.

Let me know what you think!

BarbingMay 7, 2026
What if you (could quickly)…

manually delete the offensive stuff on the first page of the all page,

replace the All page with a static page with the offensive stuff removed,

and offer a link to the current All page 1, just as it is, at the bottom.

Hope it would make defacing articles at the top of the alphabet sort slightly less attractive.

(Edit: Stumble is impacted? Could use rudimentary tricks to limit stumbling on e.g. religious content, and might consider not detailing the methods used specifically :) )

notatoadMay 7, 2026
Seems like something the ai could help you with - ask it in the prompt to return an error if the submitted article title doesn’t seem like a whimsical fake encyclopedia article title
mgmalheirosMay 7, 2026
Perhaps option 1 will be more resilient.

It could be complemented by a "Create" page for starting a new article, filtering bad titles and using a captcha to limit the vandals.

And another captcha for comment posting, which is already spammed, unfortunately.

I think a flagging mechanism will not be able to keep up with mass defacement.

Another suggestion: a daily dump of article titles, their connectivity and creation dates. I would love to visualize the underlying graph and its growth.

Thank you for such nice site!

"Despite its failure, the Great Pigeon Census of 1887 is remembered as a cautionary tale..."

This type of writing is considered non-encyclopedic by Wikipedia standards as it injects superficial analysis. The imitation articles would look better without it. Maybe train on this article? https://en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing

arowthwayMay 7, 2026
Why is this example non-encyclopedic? It's an informative, falsifiable statement that could be supported by a citation, like here: https://en.wikipedia.org/wiki/Thongbu_Wainucha#:~:text=remem...
