I completely agree with Rockman. The point of the server is to have 5 man teams compete against each other. I think we all know that. The reason people run multiple tags is to get an advantage over others who play by the rules, weather written or not 5 man teams is a rule if you ask me. Anytime one group/person gains an unfair (its unfair because you're supposed to only have 5 man teams) advantage over others I'd call that cheating.

And I disagree with qz, its not that hard to enforce, you just don't want to spend the time doing it. Not that it is a bad thing or not lets just be honest. Maybe you should recruit someone who can admin that server and who would enjoy keeping it clean. I know there is some trustworthy individual out there who has the time/ accountability to make it happen.
