I would guess that the key factor is whether or not a body part is significantly erogenous. AFAIK, many more women than men find their nipples to be a source of sexual arousal.

The key factor is the arbitrary sexual moral of the country where FB is headquartered.

I think it's more about the sexual morals of the countries where the majority of users are located.

That said, I think it's silly. They're a technology company that should be able to come up with a technical solution. Twitter handles nudity just fine.

More like the strange puritanism America can show when it comes to sex and relationships, nudity and minor curse words. Shows up in TV, eBay, Facebook and a selection of other ways. Violence on the other hand is usually permissible in near limitless quantity.

I like having my neck and ears touched. Should we ban those too?
