I should also mention we have split tests on all pages - to make sure we monitor conversion rates and adjust content based on that.
@intelliguy We have a few ways to monitor that, FIFO cookies or LILO cookies. We also monitor a few other things. Any affiliate referral abuse will be handled with extreme prejudice.
The referral program we worked on with BTS was designed to do that, but we didn't get far enough on deving out the whole workflow on some of the KYCish type of tactics needed to deal with spammers. At least not when I was working on that problem.
