My account is banned from playing Halo 5

So I just got back from Iraq and I wanted to play Halo five and got this message: Attention. At least one player in your fireteam is banned from playing Halo 5: Guardians.
My kids were playing it while I was gone apparently. What can be done to take this off?

Unfortunately nothing. The only thing you can do is create a new account to play on. Luckily thanks to the new Xbox thing you can have like 5 accounts on one system and as long as the main one has love you only need to pay for live on one account.

Butnwothout knowing how how long the ban is its hard to say something like wait it out. It could be 8 hours or 7 days

warzone should be available though in the banned account

All ban-related questions and discussion should be directed to the pinned official ban thread in the support forum:
