Well, I beleive "The Pro" over reacted, but then again he was doing his job, I think he just needs to chill a little bit, because he just bans everyone in his way.
I say yes, just because my friend (not giving out Gamertag) sent him a message saying "Hey, would you like to play a 1v1 MW2 match?" - banned, forgot how long.
Why the **** do you ban for asking a simple question?
