Its the paysite owners job to retain the members plain and simple.
Should Zorgman have been terminated, no idea i dont the rules you agree to when signing up to the PB program, is it fair that he was terminated? Hell no, if a paysite cant retain the surfers that a webmaster sends to the site, you dont punish the webmaster for it.
You look at what you have (or lack thereof in this case) in your members area and improve them, its that simple, webmasters get paid for sending surfers to our sites, if they dont convert then
WE (paysite owners) havent done our jobs you dont can the webmaster
