I plan on eventually hosting someday, but having two people who I trust very much being "plainclothes admins", who can kick/ban but when they do, nobody will know who did it, it'll just say "A plainclothes admin has kicked/banned whoever"
After the first guy trolls when he thinks no admins are on, he gets banned and goes "WTF" and then nobody else will try it because they NEVER KNOW when the admins might be watching...
