I know as a customer, you can deposit $6000 & get 144% returns after 12 days (assuming you surf 12 pages x 12 days). This would result in a return of $8640. Clearly...if everybody did this, the company would go bankrupt.
I'd imagine all their earnings are basically from those who put $6 in (or whatever amount) & never do a damn thing. It looks like they also generate quite a bit of revenue from an autosurf circle jerk - they all participate in each other's programs & just pass money around.
I just don't see how a company like that has been in business so long (mid May of 2005 it looks like) nor how they grew so damn fast:
