I agree with the poster...that is taking it a little too far.
I appreciate what they are trying to do within the auction house/ storefront with the new rules, as there were some pretty RACY cars in Forza 2.
But if what is said is true, that they pre-scan the content before enacting the ban..then I think they need to lighten up a bit on the restrictions that cause you to be banned.
I have seen other posts that people were banned for, that are questionable offenses.
In the context that the word "BR3AST" was used was perfectly acceptable IMHO. Which makes me wonder if they really ARE investigating infractions or just banning people once they see that they are flagged.
