www.pornenmeer.nl this one gets 4000 uniques per hour to his blog because he's posting free paysite videos every day.
From what I see the way to make money these days is to set up a blog, post long paysite videos (links to them) and have AFF as a sponsor. Huge traffic and I'm sure you will do fine with your AFF sales as well.
This trend will not come to an end before some serious programs take the step to prosecute these site owners. The sooner the better as I am concerned.
