I tried my name, and I don't think a single "match" is any of my (very rarely used) throw away alts ;) I guess I have a few people I talk like?

I've had several accounts over the last decade, but this wasn't able to find any of the old ones, even after expanding the results to 50 users. I personally chalk it up to my own writing style changing (intentionally and unintentionally) over the years.

The "analyze" feature works pretty well. My comments underindex on "this" - because I have drilled into my communication style never to use pronouns without clear one-word antecedents, meaning I use "this" less frequently that I would otherwise. They also underindex on "should" - a word I have drilled OUT of my communication style, since it is judgy and triggers a defensive reaction in others when used. (If required,…

Now if you only underindex on "underindex"... There's a good alternative that everyone understands, "use less"

I don't mind revealing my alts since none of them seem to link back to my main. But the top 4 results were all correct for me: https://antirez.com/hnstyle?username=gfd&threshold=20&action... zawerf (Similarity: 0.7379) ghj (Similarity: 0.7207) fyp (Similarity: 0.7197) uyt (Similarity: 0.7052) I typically abandon an account once I reach 500 karma since it unlocks the ability to downvote. I'm now very self conscious ab…

It does seem like burner accounts are effective if each account is not overused.

This is great example of what's possible and how true anonymity, even online, is only "technological threshold" anonymity. People obsessed with biometrics might not consider this is another biometric. Instead of just HN, now do it with the whole internet, imagine what you'd find. Then imagine that it's not being done already.

Except that technology is on the side of anonymity this time. LLMs can provide a pretty solid defense against such attacks — just ask ChatGPT to rewrite your message in a random writer's style. The issue is that you'll end up sounding like an LLM, but hey, tradeoffs.

Using throwaways whenever possible mitigates a lot of the risk, too.

How does it find the high similarity between "dang" and "dangg" when the "dangg" account has no activity (like comments) at all? https://antirez.com/hnstyle?username=dang&threshold=20&actio...

It has a [dead] comment that says > Please don't post unsubstantive comments to HN. [link to guidelines] My guess is it was a parody/impersonator account. You can enable "showdead" in your profile to see [dead] comments ans posts. Most of them are crap, but there are some false positives an errors from time to time.

HN silently black holes any comment made through a VPN, so I would expect a decent amount of false positives.

That’s true. The old security versus convenience hack.

But if i were a government agency I would be pressing AI providers for data, or fingerprinting the output with punctuation/whitespace or something more subtle.

Tho i guess with open models that people can run on device that’s mitigated a lot.

Should is a commonly used word and a fine one. You should feel free to use it. If someone gets hot under the collar because you said he should do something then he is an idiot. "Ought to" is essentially a synonym. Anyone that gets upset when you said they should do something but is fine when you say that they ought to do something is truly a moron.

    > If someone [test] then he is an idiot.
    > Anyone [test] when [test] is truly a moron.
These structures are worse habits in communication than subtle, colloquially interchangeable word choices.
