How porn tube sites avoid copyright infringment?

All the sites are protected by Section 520. It is the posters’ responsibility to get copyright permission, and the tube sites only have to take-down a video when notified of infringement. While major copyright owners would like to change the law, the tube sites don’t have to pro-active in preventing videos from being posted, they just have to be proactive in removing illegal content and responding to take-down notices.

Are they really though? Do they only have to remove videos that were reported, and if they are uploaded again can they just pretend that they didn’t notice? Aren’t they obligated to do as it is possible to remove copyrighted content?

I mean isn’t that what megadownload case was all about?
