@raphjd:
From all the articles I've read, gay porn has an extensive testing program compared to hetero porn.
The real problem is, that unless you lock the guys away in separate rooms, they are going to do what they want. This means that infection can happen at any time and it won't show up for another couple of tests.
In this case, guys who'll be doing what they want instead of caring for their own health would be the only ones responsible if they ever catch HIV. But those you'll do that…i'm sorry but they must be total whores.
And concerning the testing programs, i think the gay porn industry should carry out like a sensitization campaign to let people know that the testing is there, so that the porn companies dont get blamed for everything when in fact it's mostly the actors' fault.
