Banned for no reason playing Flood?

In the middle of a Flood match, co-op with a guest account. It was during one of those damn glitched matches too where everyone spawns as an enemy with DMRs and Magnums. We continue to play anyway because its sort of my creed. No quitting under any circumstances, even though the match is bugged as hell (which I reported in the issues being investigated thread). All of a sudden, I get a message saying “This account has been temporarily banned from earning xp”

Seriously? I did NOTHING to deserve this. I’m thinking that due to the bug related to joining Flood Gametypes, maybe it tripped the banhammer and earned me the xp ban. I’m actually kinda pissed about this because I have never been banned in my entire history of playing online games. While the majority will jump on this and say “if you were banned, you earned it somehow” or “Your not telling the whole story”, it doesn’t matter.

Because I know I didn’t do anything to deserve the ban. Obviously, nothing will be done about it. How long does this unjust xp ban last?

A better place for this would be to post here:
