Didn't Will_Newsome say several times that he was trolling and post material designed to get downvoted? Not sure that's quite a comparison to eridu. (To give a recent example, we banned a user from #lesswrong for mailbombing with porn sites another user; they did this partially because they were offended and partially to get themselves banned and stop spending time there. The ban is perfectly justified, yet I would not have called them a troll before or after.)

Peterdjones, too, if I'm not mistaken.
