Modern Warfare 2 Multiplayer Leaderboard before release
The X.B.O.X is trying very hard to kick the PC from it's throne as most pirated platform. The game was pirated and released on the Internet a couple of days back and many (MANY) players have already been playing Modern Warfare 2 almost two weeks before it's official release. A quick search for Modern Warfare 2 on Youtube will give you tons of videos of gameplay, but watch it as some contain massive spoilers.
Now that all those players already got a head start on the rest of us, still waiting for the game to be released, Infintiy Ward will reset all leaderboards to make things fair again:

@boyle111 It definitely looks like a full leaderboard / level reset is in order just before the release date to ensure no unfair advantages.

@jeff1315 Why would you assume we wouldn't address that at launch? Of course we'll re-level the playing field at launch.
Planning to join the pirate fleet yourself? Please keep this in mind:

@fourzerotwo Are you taking down names as you see people not authorized to play the game for future action? Piracy requires punishment.
@Sustainabillity theyre listed on the leaderboards. Logging online with a modded X.B.O.X is like sewing a big red scarlet letter on yourself.
