I wonder. When people like this come back under a new name, do they try to maintain a low profile for a bit, or start with the crazy right off the bat?
They usually have issues keeping their ego in check. Thinking they have won one over on us all, they feel a bit delusional and eventually out themselves with little if any effort from others. On the other hand, sometimes we do other things when we suspect someone is a returning troll. Can't hide for long.
