There is no way those views are coming from Facebook, the traffic is too expensive based on the rates they are charging.
The view companies are just faking the refferer. This is a common technique in internet marketinn. I used to sell clients views services like that, and I've helped videos go viral by ordering from multiple sources and getting over 100,000 views in less than 72 hours, propelling the videos to the front page. This results in the videos actually getting real organic views way beyond what was "fake."
