MCC. banned for quitting but not actually quitting

I know about this too. I literally played a few matches the other day, finished for the night, turned it on the next day and got warned that I was being idle too much. So
getting 2 perfections and capturing flags are classified as being idle too much to this game?

They do allow drop-in/drop-out multiplayer but the average player that uses this option doesn't simply quit when the going gets tough. I don't see you quitting because you're losing a match Camaro or when the other team scores a single flag or even two.
Those are the quitters these bans target. Habitual quitters who quit almost every game that turns sour for them. Using you as an example Camaro, you have certain expectations as to how the game should go. If you're faced with the worst case scenario, you
dip. You're primarily getting away from a griefer or troll of one sort or another. This doesn't happen in every match. So your not flagged as a quitter. You might have to quit 2.... maybe 3 times a night. The people getting banned tend to quit 12 to 15
times a night. Almost every match.... unless, of course, they're winning. Granted, I'm pulling those numbers out of my backside for the sake of debate but I think you get my meaning.

Yeah there is no reason to stay in a game if you are not happy. Especially in Halo 4. They allow drop in drop out of the multiplayer. There should be no penalty at all for quitting in H4. There are only a couple reasons I quit. I join another friends
game, team mates on my team are trying to destroy the friendly vehicles, or if the majority of my team is gone and no one joins. If I am not having fun, there is no reason for me to stay in a game. I play games for fun.

This is the first I have heard of a quit bann in H4. There should be no quit bann in H4 at all especially since there is full drop in drop out multiplayer. Makes no sense to have a quit bann in this game. Well unless you are quitting every single game
you play. Then thats a different story. I am guessing you would have to quit a LOT to be banned.

I only quit when there is lag (which so happens to be when the other team is doing good )
