The trouble with throw away accounts is that there is technology to link the accounts by comparing your writing style to other accounts. Hacker news had a good demonstration of that awhile back.
Some might call me paranoid, but I also change my writing style between sensitive accounts.
Not all, because that would be a bother, but between accounts where I'm a moderator and those where I'm a normal user, I make sure to change my mindset.
On some accounts, I translate everything I write twice for greater anonymity.
I probably should have just said "cross-reference," but here's a hand-wavy scenario. The gist is, the more information you have on a persona, the more you can filter out identity candidates.
So, for example, if you have unique anonymous accounts for multiple online communities but use an identifiable "anonymization" scheme (and with the right heuristics and AI "magic" this need not be a targeted attack), I can correlate and build a profile on you: Military history enthusiast, knife owner, lives in Maine, Boston U alumni, class of 2001, active hours imply working 9-5, age 39, etc.
Which is probably enough to compare against public records, leaked data, whatever, to pinpoint a single individual.
I see that implementation now says "Site is closed as of 2023-03-01". Do we know of any alternatives? Ideally I'd like to see if my HN handle brings up my reddit handle, or other cross-site linkages.
Lots of subreddits have minimum account age and/or karma requirements due to how bad the bot situation has gotten, so unless you're willing to farm karma and wait a month to post each time (or maintain multiple semi-permanent "burner" accounts, which, as pointed out by Maximus9000, can still be linked together by writing style), it's easier to just purge your comment history on a regular basis.
