This is also a concern for me but I can't be thinking all the time of who I might hurt by what I write. Otherwise I wouldn't write anything or participate on this board. It's like being afraid to walk lest one might step on an insect. That's also a kind of huge over self-importance.

I don't think there is really anymore the pure idea of anonymous posting where one sets up an account with an anonymous email and uses vpn all the time so no one knows who you are first of all. Then there are also things like prying neighbors or whatnot to contend with, if you have them in your life. You have to make a judgement that it isn't your fault that they are reading this as you have taken all effort to anonymize yourself.

The problem is any pattern recognition of text can identify many writers, who have their own distinctive style. My guess is this could be fairly far advanced if people are looking for certain kinds of criminals and their communications.

It's a little bit dystopian to figure out that there is no such thing as truly anonymous posting for certain people, even if they don't write about any specifics in their life.

I hope this makes sense!
