If you're having trouble regarding a hacked lobby on either Call of Duty, do not automatically leave your game. It will save the entire file, which leads to proxy, therefore could cause a risk for either; Red Rings, Loss of xbox live account, Netflix, Hulu, etc. I suggest if your in a horrible hacked lobby, you turn off your xbox. Doesn't matter if your friend is even hosting it.
