Well I'm sure there are many "webmasters" that commit acts of fraud against sponsors and they are the ones that ruin it for the rest of us that send genuine sign ups and not to mention Visa/Mastercard coming down on us for what others do.
I think most of the fraud comes from other countries, Russia, India etc... if I were running an affiliate program, I wouldn't accept affiliates in a lot of countries. There's fraud in the US, but it's not as easy to get away with, as it would be in other countries.
Fraudulent people
