If a character has a sudden change of (x,y) location of any high enough degree = auto ban

if a character is moving above normal posted speed = auto ban

if a character is shouting more then 3 times per 30 secs = global chat mute

if a character is being blacklisted by more then 10 people an hour = auto flag for GM's

It really doesn't seem that hard to be honest, the hard part is they're trying to be all police like sting operation. Get over it and just start banning people.
