Who identifies the porn on Youtube? According to Youtube, its regular users who police the site. Personally, I dont believe it. Whether its individuals or technology that keep porn off of Youtube, it really doesn’t matter. If Viacom can use this data to show that Youtube manages the presentation of porn in any way, then they lose their DMCA protection.

This is not a good day to be YouTube. I think Viacom is about to kick the crap out of them.
