There was a post on here about a project in stylometry that analyzed HN users comment history. The tool helped find accounts that had an extremely similar writing style to a given account. The site was soon removed due to privacy concerns but many users with multiple account attested to its accuracy

It turns out stylometry is actually a pretty well-developed field. It makes me wanna write an AI browser assistant that can take my comments and stylize them randomly to make it harder to use these sorts of forensics against me

People always claimed this as a data leak vector but I've always been sceptical. Like just writing style and vocabulary is probably extremely shared among too many people to narrow it down much. (How people that you know could have written this reply?) The counter argument is that he had a very specific style in his mail so maybe this is a special case.
reply
If you have a large enough set to test against and a specific person you are looking for, this is totally doable currently.
reply
Of course it's doable. The question is how reliable the results are.
reply
It just needs to find the needles in the haystack. Humans can better verify if they're truly needles.
reply
Not just a test set, but enough of a set to search through and compare against. Several pages of in-depth writing isn't anywhere near sufficient, even when limiting the search space to ~10k people.
reply
this is a well-studied field (stylometry). when combining writing styles, vocabulary, posting times, etc. you absolutely can narrow it down to specific people.

even when people deliberately try to feign some aspects (e.g. switching writing styles for different pseudonyms), they will almost always slip up and revert to their most comfortable style over time. which is great, because if they aren't also regularly changing pseudonyms (which are also subject to limited stylometry, so pseudonym creation should be somewhat randomized in name, location, etc.), you only need to catch them slipping once to get the whole history of that pseudonym (and potentially others, once that one is confirmed).

reply
People do change over time, I used to write "ha" after every sentence for some reason
reply
You know, i had a particularly cringy period in which i put "la" at the end of sentences.
reply
Don't throw the baby out with the bathwater. "Ooh, la" sounds really unnatural.

But on a serious note, what did "la" mean in your context? I've never seen this.

reply
It’s a common thing for speakers of Singaporean English to end sentences with la/leh. But no idea if that’s what’s going on here.
reply
You left off something.
reply
sure, not denying that. my writing style is fairly different now in my 40s than it was in my late teens/early twenties.

but, those changes are usually pretty gradual and relatively small. thats why when attempting to identify someone via writing, you look at several aspects of the writing and not just word choice (grammar, use of specific slang, sentence length, paragraph structure, punctuation, etc.). it is highly unlikely that all aspects of someones writing changes at the same time. simply removing "ha" is inconsequential to identification if not much else changed.

additionally, this data is typically combined with other data/patterns (posting times, username (themes, length, etc.), writing that displays certain types of expertise, and more) to increase the confidence level of correct identification.

reply
Stylometry is okay if you're trying to deanonymize a large enough sample text. A reddit account would be doable. But individual 4chan posts? You barely have enough content within the text limit.
reply
Stylometry is extremely sophisticated even with simple n-gram analysis. There's a demo of this that can easily pick out who you are on HN just based on a few paragraphs of your own writing, based on N-gram analysis.

You can also unironically spot most types of AI writing this way. The approaches based on training another transformer to spot "AI generated" content are wrong.

reply
> You can also unironically spot most types of AI writing this way.

I have no idea if specialized tools can reliably detect AI writing but, as someone whose writing on forums like HN has been accused a couple of times of being AI, I can say that humans aren't very good at it. So far, my limited experience with being falsely accused is it seems to partly just be a bias against being a decent writer with a good vocabulary who sometimes writes longer posts.

As for the reliability of specialized tools in detecting AI writing, I'm skeptical at a conceptual level because an LLM can be reinforcement trained with feedback from such a tool (RLTF instead of RLHF). While they may be somewhat reliable at the moment, it seems unlikely they'll stay that way.

Unfortunately, since there are already companies marketing 'AI detectors' to academic institutions, they won't stop marketing them as their reliability continues to get worse. Which will probably result in an increasing shit show of false accusations against students.

reply
Well, humans might be great at detecting AI (few false negatives) but might falsely accuse humans more often (higher false positive rate). You might be among a set of humans being falsely accused a lot, but that's just proof that "heuristic stylometry" is consistent, it doesn't really say anything about the size of that set.
reply
Hacker News is one of the best places for this, because people write relatively long posts and generally try to have novel ideas. On 4chan, most posts are very short memey quips, so everybody's style is closer to each others than it is to their normal writing style.
reply
Funnily this also implies that laundering your writing through an AI is a good way to defeat stylometry. You add in a strong enough signal, and hopefully smooth out the rest.
reply
Why are they wrong? Surely it depends on how you train it?

I'm pretty sure Epstein tried to meet with moot at least once: https://www.jmail.world/search?q=chris+poole
reply
He met with moot ("he is sensitive, be gentile", search on jmail), and within a few days the /pol/ board got created, starting a culture war in the US, leading to Trump getting elected president. Absolutely nuts.
reply
Few thoughts: in context it's not nuts at all:

- moot was fundraising for his VC backed startup during the years the emails are in, and he was likely connected via mutuals in USV or other firms. These meetings were clearly around him trying to solicit investment in his canv.as project.

- /pol/ was /new/ being returned; the ethos of the board had already existed for a long time and the decision to undo the deletion of /new/ was entirely unsurprising for denizens at the time, and was consistent with a concerted push moot was making for more transparency in the enforcement of rules on the site and fairness towards users who followed the rules. /pol/ didn't start a culture war at this time any more than /new/ had previously - it just existed as a relatively content-unmoderated platform for people to discuss earnestly what would get them banned elsewhere.

reply
Besides /new/ there was also /n/ (not at that time about transportation.) Moot's war with people being racist on 4chan had many back and forths before /pol/ was created.
reply
I always wondered how much of a cultural etc influence 4Chan actually had (has?) - so much of the mindset and vernacular that was popular there 10+ years ago is now completely mainstream.
reply
Ah, a rare opportunity to share a blog post that had a big effect on my political outlook back in 2016, Meme Magic Is Real, You Guys

Who can say what effect it had on the world, but a presidential candidate reposting himself personified as Pepe the frog was still weird back then, and at least a nod to the trolls doing so much work on his behalf

reply
Counterpoint: https://youtube.com/watch?v=r8Y-P0v2Hh0

Summary: Trump used memes not in the sense of pepes but in the original (Dawkins') sense of "earworm" soundbites, along with a torrent of scandals, each making the previous seem like old news, to exploit a public tired of the "status quo" into voting for a zany wildcard pushing for reactionary policy

reply
I remember in high school finding the whole nazi thing funny. They were literal losers in ww2. It was like drawing a communist hammer and sickle.

Looking back on it, I wonder if this was priming.

I didn't fall for it. They are still losers, but the encyclopedia dramatica with swastikas looks way way way less funny in 2026 than it did in 2008.

reply
/pol/ in no way started the American culture war. It was brewing for a while.
reply
pol was made to contain all posting on the American culture war so it could be banned from the other (more active) boards
reply
You’re acting as if https://doge.gov does not exist. Ask yourself under which presidency, administration and kind of politics such is allowed to even exist with a straight face.
reply
It would've existed regardless of internet memes, just under a different and similarly obnoxious name.
reply
Well, broke the levee if you will. Otherwise, explain Pepe.
reply
I hardly think an internet image of a cartoon frog heavily influenced American elections, despite a surface-level co-option by various Republican politicians.

I agree completely.

I'm just saying, it's a symptom. The crazy found critical mass, broke containment. From there it was laundered in millions of Facebook groups and here we are.

reply
In no way?
reply
Given the "nature" of 4chan (only a few hundred posts and a few thousand comments at a time, the vast majority of it shitposts and spam), it just can't do that. The imageboard format and limits basically prevent any scaling and mainstream success. If you follow any of the general threads in pol or sp for a while, you'll spot the same few people all the time, it's a tiny community of active users.
reply
I think the logic is Pol didn't need to reach the masses, the masses only consume content they don't create it. You only need to radicalize the few people who then go on to be the 1% of people commenting and posting.
reply
There's an old joke that 9gag* only reposts stuff from Reddit and Reddit only reposts stuff from 4chan and 4chan is the origin of all meme culture. This joke was widespread enough to reach myself and my friend group back in the day, even though none of used 4chan or Reddit.

If you radicalise the 0.01% of people who are prolific meme creators, you radicalise the masses.

* I did say old...

reply
And Facebook repeats stuff from 9gag

be gentile

We're just not going to talk about that one I suppose?

reply
'Sensitive' in this context can mean antisemitic. At least that's how I've heard this joke used.
reply
Must be russian or qatari humour <|:o)
reply
Just to substantiate this a bit: I remember a gleeful consensus in certain circles being that /pol/ and /r/the_donald had "memed Trump into the White House". It's much more complicated than that, but there's certainly an element of truth there.
reply
Then Reddit and almost all of social media went on to purge trump and pro trump content. The Donald was banned. Trump deplatformed across social media.
reply
That's true, but not really relevant to this discussion. You can't really deplatform a president; yes he was no longer on Twitter, but roughly 8 billion people listen any time he speaks.
reply
Which meeting are you seeing? That search doesn't seem to work for me, I'm only seeing the one Jan 2012.
reply
It doesn't show up in JMail for some reason, but it's this email: https://www.justice.gov/epstein/files/DataSet%2010/EFTA01852...
reply
Thanks, trying to figure out the timeline relative to the board's creation given how close they are. The first email I can find related to a meeting is this one from Boris Nikolic on Oct 20th, with /pol/ on the 23rd.

https://www.justice.gov/epstein/files/DataSet%2010/EFTA01992...

reply
I don’t agree with this analysis.

The reason I don’t agree is that moot banned any Gamergate discussion and those people then went to 8chan, a site which moot had no control over.

And it was Gamergate that put some fuel on the fire which (IMHO) increased support for Trump. The 8chan site grew a great deal from it, then continued from that first initial “win”.

reply
From moot's perspective, it can be as simple as being convinced by some rich guy you've never heard of to bring back the politics board. He doesn't need to have an intent to start a fascist coup, that's Epstein's job. GamerGate is just the point at which moot realized he'd fucked up and destroyed 4chan imageboard culture by letting /pol/ fester.
reply
That is a crazy amount of emails from/about moot...
