3 Commando Brigade

BIS and the general A3 modding community tend to deal with this sort of thing fairly promptly (removal from BI forums, Armaholic, pw6, etc). One of the main benefits of a community whose growth and success is largely based on voluntary cooperation and good will, is that it typically polices itself fairly competently. It's hard to be an asshole and not have a lynch-mob banging at your door.
