OK I have a secret email given to me by Activision to report hackers directly and have them investigated by Infinity Ward: the email is:
Please report all hackers, Prestige Glitchers, and XP lobbies to the email. Let's get them out of the game!!!

If you think that reporting hackers is going to do you any good....more power to you. You have a better chance of striking oil in your backyard than you do in having someone banned after you report them.
