Trash ban

On halo MCC my friend who has been grinding since launch of halo reach and is currently level 99 but is now not allowed to earn xp until 1/15/20 what is this bs you earn only 1k a game and at his level being afk is just useless

Please use the ban thread pinned at the top of the relevant MCC forum for any queries on matchmaking bans
