I was playing the game just now, for PC, and this asshole named Mojo was using an aimbot.  It was pretty obvious because in the kill cam I could see his aim spin around and snap directly onto my head.  Everyone on my team was complaining about it, and to top it off, he got the game winning kill, so everyone on both teams could see him cheating.  So how do I report him?  I googled it, and found out I should report through the Steam players list, but then people said that's just Valve and it doesn't do anything.  So is there a page to report hackers somewhere straight to Infinity Ward?  He was level 70 also, so who knows how long he's been cheating.  Asshole buys the game, then buys an aimbot, and then gets banned and his account deleted; that's what I want to see.
