If we allow cartoons to slide through our iron fist, then someone is gonna want us to allow paintings of nude women because of "artistical" purposes, and then if we allow that, someone is gonna want to allow them to post up their PhotoChopped nude pic of Britney Spears... you get the picture. Besides, we don't even know where the host draws the line for nudity, so in the unlikely case that they ARE monitoring the site, it's better to be on the safe side than on the road side offline looking for a new host.
