Sponsor Stealing Sales?
 

I do not use these guys but it has been pointed out that anyone who promotes them you do so via iBill.

actiongirls.com
viewpornstars.com
(I do not have an iBill code so use your own)

When iBill started it's problems they setup up Verotol to process all Visa sales. If you check your links and go to the join pages you'll see:
Pay with Mastercard/Discover and that is iBill
Or:
Pay with Visa and that is Verotol.

And to make things more weird. If you go to the site direct without the iBill tracking code the join pages are for ccbill instead of iBill.

Essentially this sponsor has switched processers for Visa so affiliates are not getting credit for the sales by surfers using Visa cards. :(
