How do you know she was positive for 7 years?

Renee Pornero, Jessica Darlin, Arianna Jolee, Cris Talina are just some of the girls who did some evil angel movies bareback with trannies, yet I doubt anyone is taking any more caution when working with them or when working with someone who just worked with them. The industry is deluded and everyone has an it wont happen to me attitude all the time. until someone is revealed to be positive, there is no blacklist.
