I thought those banners only came up on videos that sites posted for THEIR own videos. See an Evil Angel video, the banner will direct you to their site. Lots of examples like that.
Hell, here's another one of Alysha:
This was a content share video Alysha did with Anna from 4RealSwingers.com. And, while we aren't thrilled with them using it on XVideos, it is clear that's where it came from. So, why are we getting links to Puba on our videos, which are stolen to start with?
Forgive me for not knowing the ins and outs of the tube world... I try to stay off of them except to send DMCA Notices. But, I've been looking and I don't see any random ads going to sites that aren't affiliated with the video.
