For years we have been playing in games with hackers, modders and straight cheaters. I have seen modded logos, emblems, weapons, weapon abilities, killstreaks, controllers, leaderboard fixing, going outside of the map and lag switching. I am sure that the list goes on much further than that. The point is that there has never been any true consequence for tampering with the games in these ways. Maybe a person would be banned under a certain gamer tag and lose their account stats, but that has been the extent of the punishment for these actions.
