Wow. This gives a lot of false positives, but it found all ~10 of my old accounts over the years. The most interesting thing is that my writing style changed pretty drastically since a decade ago. Searching for my oldest account matches my earliest usernames, whereas searching this account matched the rest. The details of the algorithm are fascinating: https://stylometry.net/about Mostly because of how simple it is.…

Woof. I create new accounts on a semi-regular basis because I think cliques are the most corrosive factor to social media. Any time my account gathers enough upvotes enough I destroy it for another. I had four accounts. None are over 50% confidence, but when I look at any one account the others are consistently #2, #3, and #4. Now I’m thinking very carefully about what words I use to avoid linking this as the 5th acc…

Have you tried including parts of speech (for example, as bigrams and trigrams) as part of the features considered in your model? I’ve had great success with stylometry that goes beyond TF-IDF with bags of words; including grammar patterns was shockingly good. (FWIW, it didn’t find my throwaways; my own model didn’t, either, because I knew that word choice wasn’t enough to avoid being outed by stylometry) Edit: by bi…

> Edit: by bigrams and trigrams, I mean reducing word to their parts of speech labels and using THOSE as word tokens. You’ll find that native English speakers have higher weights on some phrase construction patterns than, say, folks from Romania. TF-IDF is useful for these POS-grams (just made that word up) as well.

That is a very good idea and when I update the site that will almost certainly be included :) Any other tips? Been reading papers for ideas and I think I may have to ditch the cosine similarity and go for something fancier soon. Thank you

> 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.

Is this? I thought that it was ok to have throwaway accounts, as long as they're not specifically to avoid a ban or something like that.

This could be a good idea for identifying bots.

Not sure if GPT3 at least if prompted right would have clearly identifiable style. Could probably detect converted call centers in Russia or Cambodia where 50 employees post on 10000 accounts though.

Earlier quoted context omitted.

Why would montrose be pg ? The correlation is not that high. Looks like a few people have picked up pg's mannerisms.

Yeah, that score is only slightly higher than the highest one it shows for my account (which is also bold) - and unless my alter ego has been disguised so well it even managed to hide from myself, I'm pretty sure that isn't me :)

The score for montrose vs pg is lower than the score for someone most similar to me, who is definitely not me.

I think, the similiarity has to be in the high .80's to suspect that it's the same individual.

Well now I'm self conscious about my closest match being an 0.34 when so many other people are reporting much closer matches with accounts that aren't alts. Do I write weirdly?

.31 here! I'm a non-native speaker tho, so it wouldn't surprise me if I had weird speaking habits
