I'm also intrigued by his concept,
I've taken a look at his source code, he's passing your account info to the pop-up when you click on one of the items. Put I tried to get the sorcecode of the pop-up but it just returns me the code of the main page. Now i'm no coding expert, far from that but If it's actually filling out an affiliate CPA offer everytime you click on one of the prize items well for sure hes cashing out BIG TIME.
