When you get retards like this, just do vote_kick.
All votes go by popular vote, if YES gets more hits then NO, they get kicked and banned for 15 minutes. (yeah, my vote kick system is actually useful unlike 99% of other votekicks that just kick and the retard can just reconnect... how useful

)
I'm going to implement aliases for the command eventually because a lot of people try votekick, votekick in chat, or vote_kick in chat so I'm going to make the system compatible with that.
