If you start filtering for child pornography, and people know about it, they will come at your hard if you miss anything. Even for a technology that gets all known child porn videos, people would be beating down the door to sue/bad mouth Facebook for missing the new ones. Mostly due to people being people, but also because the technology is 'magical' to far too many people in society so they feel like there are no limitations (or it's hard for them to grasp them).
