You can use /ignore cn to ignore someone, i.e. not receive any of his chat or voicecom messages. Actually muting someone has been discussed already, and it does make sense (as someone put it, "we're okay with you playing, just shut up"). However, I'm not sure if that would actually be better than /ignore, since some people get offended by things others just find amusing, etc.
