Is very confusing, it's a lot of hassle to manage and maintain an adult Facebook page and getting banned for a stupid thing like half of nipple or even for pictures that you can't see nothing at all but clothes.
However they are generating pages like this ones:
https://www.facebook.com/pages/PornT...9335909096638#
https://www.facebook.com/pages/Porn-...84769394936100
So if so many people are interested, obviously are more than this, why make a drama out of it?
