Don't feel bad. A friend of mine studied the T&C and guidelines closely and noticed that it said that nudity depicted in classical art was exempt from the "no nudity" rules.
So, he posted a image of a really old painting, can't remember which one, but in excess of 200 years old.
Temporarily banned for a month!
Appealed by pointing to the clause stating the exemption; Banned upheld after human review.
