Before someone should send game film in??
We've all have "poor sport" encounters, some more than others, but at what point should I be sending film in? 
Personal attacks? Homophobic slurs? 
I'll do the ".report <PlayerID>" if the private messages start coming in, usually followed by a squelch. But again, what is the threshold to say, ok, this guy is really ruining my gaming experience and someone needs to be informed of it...
