Jimslip makes a great point about so much porn being taken for free that eventually it could well kill the industry dead. I think it may well do for small independants (like in the recording and film industry) but the big boys of porn will probably still be there making handsome profits like in the those other industries.
And while I understand the points offered up by those having a vested interest in porn production in whatever capacity, but can all those same people say that they've don't own or have never seen a copy dvd of a mainstream film, bought a fake top, pair of jeans or such like?
