You should probably relax a bit Digglez. This community isn't much worse than any other community you'll find now a days. The only reason some appear better, is because the game's mechanics don't make it easy to troll. Take WoW for instance, horde and alliance can't even talk to each other. That's not fun and the only purpose it serves, is to keep people from trolling each other. There isn't even friendly fire in most games either but if you look for a game that does have the things warband has, the community is exactly the same. I'm not saying it's perfect, and I'm not saying that just because the average game is terrible(though I'd argue just how bad it really is) that it's acceptable to leave things as they are. What I am saying though, is that you need to lighten up and stop letting every little thing get to you.
Considering he has multiple bans in his history, it would most likely be more than just a day.
