There's also someone, or some people, clearly practicing their creative writing or something. Usually they make an account, post something weird to asklemmy or a similar community, and then delete it within 4 hours or so.
Usually it's a "stupid" or obvious question, with some vaguely contreversial twist. Like "My boyfriend has problems with how many guys I've fucked... but I also used to be a sex worker". Stuff that's within the realm of possible, but not particularly common, or where you'd expect the asker to already be aware of the answer/reason.
They get a few hours of engagement, most of the time don't engage in the comments, then delete the whole thing.
