He used this to advertise Google Is Hiring: Work from Home credit card rebill offers. He told me he made $80,000 in the four days it took Facebook to discover it.
It was a cat and mouse game between Facebook and the affiliates in those days. This was after a short period where Facebook itself allowed these credit card rebills to be advertised on the site.
Affiliate marketing was a nice cash infusion for me at the time, but I am glad to have walked away from what is really the bottom of the barrel in the internet marketing world.
