I had recently been banned from earning credits and temp banned from online play after every single game I leave. The notifications pop up Everytime I open halo reach. It has gone on for two weeks and I never hacked the game please help me 
The prophet of the ban thread has brought you a link to the Reach Ban thread. Post there and I’m sure someone will explain the reason for your ban.
