What would happen if treyarch catches you boasting,cheating?black ops?

I believe the term youre looking for is "boosting", right? When you and a friend enter a game to kill each other for headshots/killstreaks? It depends on the amount that you do it, punishments range from stat resets (they can reset you all the way to level one, no prestiges) to permanent bans from CoD multiplayer. It's not worth it, someone will notice if you use the Nuke like 10 games in a row.
