unfair permanent ban

Hello, I was playing the new crimson map online when I was randomly kicked off. I had a message saying I was banned permanently, I was not done anything but play. I only got my gold membership a few weeks ago and I have fairly bad lag. Please explain why I have been booted from online play.

Please use this thread for bans related to Halo 4:
