I shoot amateur girls modeling nude and the affiliate conversions have been very good. I shoot every week and I also update the website every week as well. The site has a very high member retention rate as a result of it, and PLENTY of new signups too - all throughout the day and evening - every day and every evening. I've had the site for nearly 16 years now. I use CCBill as my processor, so all of the affiliate payouts are handled through them.
The particular girls that I specialize in shooting for
True Amateur Models - (Trueamateurmodels.com) are indeed 100% real amateur girls. I know for a fact that they're real amateur girls because I recruit them myself to participate in my homemade and amateur nude modeling shoots. The vast majority of the girls are recruited as a result of my speaking with them out in various public locations such as shopping malls, amusement parks, public beaches, etc.
