If someone is that concerned with stats and cheating that they'll go to the effort of buying a second copy of the game, a second Xbox, and a second live account, not to mention having a second network connection, screen and whatnot, just to be able to cheat in an online match, then I say, let them do it. If someone wants to go to that much effort in order to know my location in Rainbow Six, for example, then they've got some serious problems.
