If you're the slightest bit competent then you shouldn't ever get karma banned while playing "acceptably". I kill inos because of traitorous acts all the time and have yet to even get close to a karma ban. Give adequate warnings and don't bring an RPG to a knife fight. If you're in a crowded room as an innocent, don't try and nade a t in there, it's common sense. Or give adequate warnings to your t buddies
If everyone played serious as you. Probably 3/4 server would be karma banned. I believe some rules were implemented to slow down players on karma bans. More fun enviroment where people are staying.
