On their website, the limit is now 40 years old.
But, African Americans are not always welcomed, if the comment of Hoot at Waybig is to be believed.
I REFUSE to do any other business with Sean Cody or their racist, derogatory site ever again. I've been working recruiting people for this site... I referred a few people and a few people got booked, including a model who did about 6 films this year. I never got paid for recruiting. I figured, as a fan of the site, I would refer people to it and give SC the business. And it would be somewhat a fetish to see people I know doing this. So I did, and I got an email a few months ago saying "biracial or mixed applicants are a dime a dozen and not welcomed. It is hard to get them approved unless they look a certain way". The people I referred were African American males who were in good shape. However that did not matter. If they are not white, they do not want to book them. I had sent an email to SC about a model who I know and asked if he was a fit (mind you I sent this email over a month ago), and I get one back saying they do not want me as a customer or to do business with them ever again, per their "legal" department.
