I recommend Crytek to disable special characters in nick names so cheaters can be kicked/banned easier. There are lot of complains ppl can't kick cheater from server because he has complicated name with special characters. That's not so hard for Crytek to do, but it could be step further in measures against cheaters/hackers.
Actually, IDK why ppl have to make their name so complicated anyway :/
What do you think about this?
