Penalties are applied no matter who was playing at the time. Bans will only be overturned if we determine the infraction was due to unauthorized activity on your Activision account. Temporary bans and accounts in a limited matchmaking state cannot be appealed.
Members of a player's party may also experience limited matchmaking while partied with a player in this state. At any time, the account may be returned to normal matchmaking, placed in a limited matchmaking state again, or it may receive a temporary or permanent ban.
