Halo 4 does not work the same way Halo:Reach did. You do not earn points through campaign anymore unless you complete a challenge. You are not banned, you just need to go into matchmaking or Spartan Ops if you wish to earn points. Simple answer: You aren’t earning points in campaign “anymore” because you never were earning points for campaign with the exception of campaign challenges, which are daily or weekly tasks you can complete for points.

you are proboly xp banned, the game thinks you are boosting
