I know alot of people love to swear/curse whatever you want to call it, even I do but i try to use it less, If you are going to joke around and use swear words please only do it in xfire or private conversations. Cursing outloud is not allowed in CM, we accept the odd accident when you accidently forget, we've all done it.
But constant cursing will result in a few minute mutes then a whole match mute then kicks and eventually bans.
