Last year I had a frustrating experience with this type of thing by linking to Margaret Cho's blog (the comedian? gay rights activist?) which apparently CCBill blacklisted for using banned words. Here's more info:

I learned that it does no good to reply to those emails, and you need to go over those guys' heads to someone at CCBill who can actually make a decision otherwise you are beating your head against a brick wall. When I talked to someone higher up they stopped bugging us.
Another one of my favorites is someone who got a violation notice for bestiality because of a photo set where a guy was dressed as the easter bunny fucking his girlfriend.
