Could someone maybe explain why anybody might intentionally post as plain GUEST? I mean, not even a temporary pseudonym to indicate that two posts come from the same person.

Maybe there is someone who used to do it, but doesn't now, who can suggest a reason or two. (I'm afraid I've decided never to enter into any kind of direct discussion with unadorned GUESTs, which may seem unfair, but it is based on hard experience.)

I'm not being sarky here, I'm genuinely curious, because I can't think of any reasons (apart from simple shit-stirring of course, but I'd like to think there might be something more to it than that).
