Honeypot to see what accounts are tested in sequence? ;-)

I turned off nginx logging if that makes you feel any better. Of course there's no way for you to verify that because I'm just a random guy on the internet but I will tell you that I am a civic minded citizen who is concerned about privacy and the Internet.

Anything like this for Reddit? Would translating to other language and back defend against this algorithm?

Yes. But then you have to send your original comment to a translation…

I'd say you should. I'd rather see this as being publicly and freely available to everyone rather than some shady "Big Tech" analytics company.

If the "weapons" exist, I would feel more comfortable knowing everyone can access them, not just an elite that can use it for their own (selfish) purposes.

After a few tries on boring accounts, I thought to try the account of somebody who was notorious for an incident outside of HN, and had a (deservedly) bad time at HN for a couple of years before the account went dark.

And yeah, there's a bunch of high confidence (.6-.8) hits for that account, and from a quick browse of the comments of the recently active ones, they look really likely to be alts. Like, all three that I looked at had comments that made it very clear it was this person writing pseudonymously. (E.g. writing on their signature issue, and saying they couldn't go into more detail due to fear of self-doxxing; or somebody literally saying that the alt's claims reminded them of the public writings of the notorious guy years ago).

Obviously I'm not naming the account, but this functionality turned out way creepier than I thought the moment I tried it on the account of somebody who has a reason to disassociate from an existing public persona, but still wants to participate here.

nice one. are you using gpt3 under the hood?

I'm not that smart - my site is basically just doing some calculations on word frequencies. You can read https://academic.oup.com/dsh/article-abstract/17/3/267/92927... and https://www.tandfonline.com/doi/abs/10.1080/09296174.2011.53... and https://news.ycombinator.com/item?id=33755898 for more information.

I've complained a lot about Haskell and now it thinks I like Haskell =(

Needs sentiment analysis IMO, otherwise you'll get "Here's a bunch of people who are JUST LIKE YOU", except they use a similar grammar style but hold opposite opinions on the same nouns.

I really liked the informative and straight-to-the-point about page - describing how the algorithm works in a way that is easy to understand. All the important details are summarised there. Well done!

Edit: From the "How to avoid .." page, there is the following sentence:

> Also, most authorship identification algorithms have poor accuracy when working with small amounts of words. This means the optimal strategy would be discarding an account either after every comment or after a small number of comments. Unfortunately, this is against HN rules and may result in a ban.

Can you clarify what this means and why it would result in a ban?

Serves you right for disparaging The One True Language!

Ok, fine, we'll present Idris with a fig leaf.
