Well, what did you say? Given the state of the game right now, I have to believe that your situation was personally looked into by someone with some sort of authority. I HIGHLY doubt that you've been banned for dropping a mere "Fbomb"...
If I had to guess based purely upon my MP experience thus far, the chances are high that you're probably some sort of the deus vult/white supremacist trash that infests this game. If not, I hope it get sorted out quickly. If so, I applaud TW for taking steps to remove degenerate filth from their product.
