I would agree. However, with the number of performers that are on Myspace and Xpeeps, it isnt that difficult to try to contact a few for advice before entering the business. It may not be the most effective means of gathering advice but it is a start.
As for the pornstarperformance angle for directors and producers, that could be problematic. Pornstarperformance is not a great idea to begin with. First off, I've seen posts made by directors about talent that borders on slander/libel. Adult employers, and thats what producers and directors are when they hire talent, are bound to the same laws the rest of us are. If you were attempting to find another job, would you appreciate your former employer posting on a public website that you were lazy, inefficient, often late and took long lunches? Employers in California are limited to what they can and cant say when they are asked by a prospective employer about recommending a former employee.
Giving irate adult performers a podium like that would probably lead to a website that was more a complaint department than truly helpful.
With any career, there is a learning curve in being an adult performer. Until a performer gets into the business and actually starts performing for different studios/directors they wont know who they like working with and who they dont. The same holds true as for other talent. It will take them a while to develop a no list.
My general advice remains to most female performers dont do anything or anyone that you dont want to. Walk off a set if you think you are being taken advantage. Do your homework.
