Banners and offers the same everywhere!

Hello everyone!

As I progress in this business, I’ve been noticing that on Traffic Junky websites such as, Fapdu, Xtube, Xhamster, etc…
I see the same variation of banners connecting to the same offers. I can refresh over and over again.. And the same banners will rotate with the same offers.

I guess what I’m trying to understand is, there must be tons if not thousands of affiliates doing adult desktop but it appears like there are so less variations being offered ( banners/landers/offers ). ...
