This is a troll and a ban evader, he has already managed to register more than 7 accounts, of which 5 were banned.
I guess his accounts are only active in the Russian local or possibly also in boards I don't visit because I don't remember ever seeing any posts of those accounts in the forums I frequent. He isn't even trying to hide the connection to his older accounts since he uses similar usernames as those that are already banned. I don't understand people like that who hate this place and its members, and keep going back only to remind everyone of those facts and tell them how much better they are.
