Haha he does this for years - technically he does nothing illegal, but the tarffic is worthless, it's comming from his farm of free porn sites. Those domains also used to be free porn, then he pulls them for sale, as long as he keeps the links, the traffic will be there. After couple of weeks he pulls the links and traffic dies. He keeps getting banned on Parked, Afternic and he always bounces back.
And of course the traffic is absolutely worthless for advertisers...
Now i know "no comments in sales threads" so admins feel free to delete it and let some people burn their money, your karma, I do not care THAT much...
