I've played a total of two matches in multiplayer and svcked royally at them both. But to my dismay, I logged in tonight to play a round and noticed I had suddenly been boosted from level 5 to level 10, and have 200 some kills that definitely couldn't be attained in a matter of playing for 15 minutes total. My only concern is getting banned for something I haven't done.

Anybody else experienced this? And who should I contact?

Quit lying. You boosted. Now tell us how you did it.

I wish I knew, bro.
