Facebook Spam - How do they do this?

I keep seeing this shit pop up on Facebook.

My non internet marketing Facebook friends keep posting these ads to Rayban websites obviously unintentionally. They end up tagging hundreds of people when they do this and thousands of people see the posts. I'm sure it's paying off for the guy who created all this. I've never tried this type of marketing before but it looks interesting



Any ideas??

its most likely some type of fb viral app that tags all friends to a post super blackhat ....but profortable if pulled off correct
