Got Banned for no reason on mcc

So I just logged into mcc on my xbox 1 and after finishing a couple campaign missions for Halo Reach I decide to play Online to rank up then im banned for one week.Note that I have not played in 2 days.

Dont know if this is a good answer, but you might’ve left your game on and it might of matchmade. Idk

Bans for 1 week mean your account has been caught AFKing, Swordlining or Macroing. See my post here for further details:
