report the UFO/flying hackers to sony...just put any game and at the bottom highlight that it is COD4 you are actually reporting....sony will ban them, not just the account but the playstation itself will be banned from connecting to P/S network.
they can view what each player is doing live and keep it for 3 months....be warned...
