I should mention he was reported in game for Ghosts Online Code of Conduct because he stayed long enough. Most of the hackers are smart enough to disconnect earlier so you don't have time to report them in game.
I understand your frustration, but name and shame is not allowed on the forum.
Please continue to report players in-game who violate, or you suspect of violating, the Ghosts Online Code of Conduct. This is the official and most direct course of action to notify Infinity Ward of player misconduct.
Helpful tip - Players who leave the lobby quickly after a match can still be reported through the recent players list. To access this list, press the F1 key while at the multiplayer main menu and a new window will appear. Click the arrows over until
Recent Players is displayed. Scroll through the players and select the one you wish to report.
