I was playing Halo 3 online the other night, and my internet connection sucks, so it was really laggy and stuff, but after the game in the lobby, the little advice and tips message in the bottom left corner said something like, "Bungie is watching you: Cheating is being auto-detected, consider this a warning!" And it reappeared a few times, does that mean, they found cheating specifically on my Xbox, or does it mean that they can auto-detect cheating and are just telling everyone. Because I wasn't cheating!
