Oh wow, it's really sure that I'm stavrosk, which I am: https://stylometry.net/user?username=stavros The next person is 30% less certain, that's huge! This would basically identify any alt I might have with near certainty.

Funny thing is, it thinks I'm you, but it doesn't think you're me!

I'd have thought this stylometry thing would be commutative.

Or something purpose-built like Anonymouth ( https://github.com/psal/anonymouth ), although it seems to be both unique and dead. Also interesting: > Ross Ulbricht aka Dread Pirate Roberts, the mastermind behind the infamous Silk Road site which served as a black market for drugs, weapons and fake documents was also well aware of the potential danger of stylometry being used against him. At the time of his arrest in a…

I mean he used an forum account with an email that had his name in it.

That's the problem - it only takes a single slip and it is recorded forever. Perfect opsec is an impossibly high bar if you are maintaining an active online presence.

That’s why I always use throwaway :) everywhere. Reddit. HN. Twitter. Everywhere. I’ll spam every site with my throwaways. Long live throwaways.

That’s the point of this post, that you are not safe by throwaways at all, because all of your throwaways can be linked together purely by your textual style.

> but the cat’s out of the boot It's my first time hearing that variant. Usually its, "the cat's out of the bag" where I'm from. Do you mean boot in the UK sense, what Americans would call the trunk of a car? Or do you mean a sturdy piece of footwear? Obligatory xkcd https://xkcd.com/2390/

It’s a little writing trick I leaned from (I think) Orwell. Any time you’re about to use a common metaphor, try to tweak it. You’ll catch readers off guard, which piques their curiosity. It’s a fun game, too. I wish I’d used “the cat’s out of the hat,” but I didn’t think of it till later.

I like mixing metaphors, in this case "the cat's out of the tube". ("the toothpaste's out of the bag" doesn't work as well though)

I changed my nickname so my employer can't find me here. I'm not amused by this.

If this basic implementation can catch you, I’d consider it a friendly reminder that changing your account name is not a very effective means of adding privacy.

No mechanical means, but I have referred to a thesaurus occasionally. Mostly I tried to change my sentence structure, not just words. It requires actually thinking differently, in a way. Which makes it difficult to know how well I'm communicating.

I imagine this would be quite difficult in practise, due to all the subliminal factors behind a person's writing choices. For example, as somewhat illustrated here, your personal vocabulary is a kind of fingerprint. As you mention, using a thesaurus can somewhat alleviate that, but if a thesaurus is only changing a small % of your words, then it will only have a suitably small % effect upon analysis. To go yet furthe…

I wonder if someone will come up with a Grammarly-like tool which you can feed with sample writings to help you increase/lower the similarity score of a new text you are writing.
