Facebook censors 30,000 year-old Venus of Willendorf as 'pornographic' (theartnewspaper.com)

I don't think this statue is porn but I can understand why it could break Facebook's rules. Context is important. A photograph of a naked woman in a biology textbook isn't porn, but if you upload exactly the same picture to Pornhub it becomes pornographic. A statue of a naked woman in a museum clearly isn't porn, but that doesn't mean it can't be regarded as porn if you upload a picture of it to Facebook.
