I don't know bro.
On EU servers I never run into any problems with the admins.
On NA I get muted a lot for no reason (sometimes kicked), but ever since the december patch (when the admins were changed), I haven't been banned (except on Scot's server, but that server is clearly a joke). And let me add, I flame the admins a lot (but to be fair they start flaming me first (this is also generally when the mutes come in)).
