There's a forum dedicated to outing and exposing the models on Girlsdoporn. My first thought when i went through it was how are these guys able to recruit not only beautiful girls, but many of these girls are pretty accomplished. There are girls who played sports at major universities, an attorney, a girl who does animation work for Disney movies, an activist for a middle eastern womans rights group, a couple of body builders, theres been two beauty queens, and they were winners, not just participants. Those are just the ones off the top of my head. I read somewhere they literally scour Instagram all hours of the day just looking for models and semd them a message.
