I was playing mw2 on saturday after the UFC and a few games into my playing... I found myself in an endless match. I checked the score and the top 4-5 people all had 500,000+ scores WTF!!!

apparently the host was using some sort of hack to where they made a private game and got it into the public queue or something like that.

Played for around 45 minutes and got a bunch of attachements and probably 50,000pts before the server lagged out and kicked everybody.
