to awaken this giant...
tonight i was playing some slayer and me and my guest were booted twice. both of the times neither of us were around anyone, and the screen just popped up saying we had been booted. the last time it was a ranked game and we were up by about 20 kills on the other team, and that screen pops up. this may have been an issue dealt with before, but what's with me getting randomly booted?
You were probably being "bridged." It's the new stand-by (the concept of cheating having a fashion-like sense of been-there-done-that makes me want to put a gun to my head), and basically whomever is "bridging" can select who they'd like removed from the game. It has to do with tracking the IP you're associated with, and banning it from that instanced game.
Don't ask me any of the technical details, because I don't know any. It really sucks, but that's been the case with matchmaking ever since stand-by was originally exploited. You just gotta trudge through it and pray you don't catch it again (which, unfortunately, is almost impossible in level 30+ play).
