"The bare breasts and buttocks painted by our artist are considered by you to be inappropriate. We have noticed that Facebook consistently rejects works of art by our beloved Peter Paul Rubens," over a dozen top Belgian art officials wrote to Facebook CEO Mark Zuckerberg.

The Visit Flanders tourist board even produced a mock news video where security officials prevent visitors from seeing nudity in the Rubens House museum, one even spreading his arms in front of the Adam & Eve painting, where the biblical figures are covered only by the proverbial fig leaf. Instead they divert them to other paintings where everyone is properly dressed.
