Good question... I couldn't tell you about some of those things because I am not an adult performer. But I can tell you that Hannah Harper is basically the PR woman/mother of the agency in that she treats the gals fears, emotions and takes care of them.
I am not an industry expert...never claimed to be... prob never will be. But I do know that every agency (World Modeling, ASS Inc, Exotic Star, LA Direct, and Spiegler Girls for example) have had people bitch moan and complain about the agents.
All I know is that LA Direct gets the young ladies to the shoots, the women make money, and they have a large and talented stable.
