See the classic Gwern post: https://gwern.net/death-note-anonymity

Which quotes Tao on using deliberate disinformation to preserve anonymity.

> …one additional way to gain more anonymity is through deliberate disinformation. For instance, suppose that one reveals 100 independent bits of information about oneself. Ordinarily, this would cost 100 bits of anonymity (assuming that each bit was a priori equally likely to be true or false), by cutting the number of possibilities down by a factor of 2100; but if 5 of these 100 bits (chosen randomly and not revealed in advance) are deliberately falsified, then the number of possibilities increases again by a factor of (100 choose 5) ~ 226, recovering about 26 bits of anonymity.

Intentionally adding writing "tics", scheduling posts to appear between 2am and 6am in your timezone, or pretending to have a different gender/location/age should help a lot in staying pseudonymous for a while longer.

I was thinking this. Why not just lie? Come up with personas, stack them on other personas, and eventually you're pretending to be a 23 year old Asian man from California who is pretending to be a 50 year old New Zealand carpenter and half the bits are muddled.
What are you writing about? The real person is going to write about what they know, so when the topic of housing comes up, and they pick New York City to discuss zoning restrictions, sure it's possible they're in New Zealand or California, but it makes more sense to assume the user behind the keyboard is in NYC. The question is, for what purposes is the user trying to be unmasked? In the world we live in, the entirely boring purpose is to sell them ads.

I disagree that ads are the only reason to dox someone. I assume that few pieces of writing would be controversial enough to warrant a fake identity, but those few would be important.

If I wanted to pseudonymously accuse a mayor of corruption, I think it would be safer to generate true stats and interview real people, but do so in an area I don't live, with some anecdotes where the facts don't quite match my life, using language that has been edited by a friend with a different writing style.

This is why I follow subreddits for cities I have never been to.
Possibly, but it can be very difficult to conceal age or location reliability, especially as your corpus of text grows. And of course that is with just the text, when you start adding in other bits of digital information it gets even more difficult.
