Upcoming Halo: The Master Chief Collection Content Update Notes
    Implemented new systems and temporary bans for matchmaking penalties. These include penalties for:
        Quits
        Betrayals
        Idling
Note: Leaving the game before finishing (any time from the start of voting until the game concludes) will result in a loss for your ranking and a penalty to your Xbox One reputation. After this update, if you quit, betray, or idle too many times during a set period of time, you will be temporarily banned from playing matchmaking. If you continue to engage in negative behavior after the temporary ban has lifted, you will continue to receive temporary bans that are subsequently longer in length.
