Reach ban

So last night I get on to play some reach and my console is temporarily banned this has happened before as my 4 year old has his own account and plays as well. How long does the ban last I can’t seem to find anywhere to look up what the offense was? If anyone could help gamertags are attached thanks in advance!

Are you sure your console is temporarily banned and not temporarily banned from Reach?

Which console are you using? (360 or Xbox One)

For console bans, there is nothing anyone here can do and your only chance is to contact Microsoft.

If the ban is for Halo: Reach itself, outside of cheating, you can be banned for idleing in matchmaking (AFK and not playing the game in Matchmaking), Credit boosting, Credit exploiting, Network manipulation etc. You can find more information about Reach bans at the home page of this forum, it is a pinned topic with all the information you need.
