Cutting off communication with everyone else in the entire game is kind of defeating half the point of multiplayer in the first place.I disagree regardless, over half of those problems can be solved by pressing F8 and ignoring or going to some other place where you can change your nickname 100 times. In fact, some of those things listed are the reasons priv and scrim servers always have problems with aliasers.
I can understand distaste for dickweeds playing coy or impersonating in priv/scrim servers. I'm a sympathetic man. Cockmasters to the max, bro.
But trying to use it as a general rule doesn't really work.
