So you asked why he got the ban, everyone in this thread told you, he is quitting out of too many games and lagging out counts as a quit. Also, even if he only quitted like once a day, the game still keeps track of all quits. It doesn't matter if they are like a week apart or so. If you still don't understand why your friend got banned you seriously must be a dumbass. And to prevent this from happening, don't quit out of games? Kind of obvious.
