@ryo @udon It's pretty rare in my case, but in some boards I have read posts before that made me think "wait, did I write this?", and sometimes I didn't (sometimes I realize that actually, yes, I did write that many months in the past). Also, some other posts sound like they were written by someone that read a previous post of mine somewhere else. Kinda interesting. Though of course, I can blend in if I want to, in places with no usernames. Difficult to do with higher-quality posts, though. But again, a small number of people do write similar things and/or in a similar way, because they have traits that lead to the same type of writing. I actually don't know how many, they could all be just one person as far as I know.
