Actually Grennie, I'd disagree. 'Feminist' porn is gradually crippling the industry.
My definition of feminist porn (which will naturally be disputed, but here's just my opinion) is the kind made by women without engaging with the industry at all. A lot of cam-girls (yes, they often have to join larger sites, but with nowhere near the contractual obligations) make money in this fashion; Who is exploiting them?
And of course there is the porn made by cheerfully exhibitionist couples (I've known a few couples where the woman was primary instigator!).
Both of these are causing huge problems for the industry because they are made free and broadcast free. The demand for them is growing; it's just hard to quantify because it's so non-commercial and mostly expanding through online communities rather than broadcast sites.
I suspect that as more women abandon the internalised patriarchal 'women are victims of sex' attitude and embrace the freedoms they've been denied for so long this factor is going to only become more prominent. In the same way as big budget porn was edged out by gonzo, gonzo is being gradually eliminated by crowd sourced erotica.
enlightenmequick I have seen some absolutely horrific porn. I have also seen the watermark that confirms that a law enforcement agency has also seen the porn and checked to ensure full compliance and no basis for illegality. I have no doubt that there are instances of genuine exploitation in pornography and due to the sexual nature of the industry it is a worse event than it might be in any other job. But these are specific instances of violence, rather than situations endemic to the industry; They are investigated and if prosecution is warranted then directors, producers and actors have been imprisoned. The reason so few instances of this type are reported is that there are so few of them; the commercial porn industry is, quite rightly, under huge and constant scrutiny.
The situation is not ideal; but I'm not prepared to support the statement 'all porn is violence against women' when not all porn features women, not all porn features violence and some of the porn that does the women are not just consenting but actually enthusiastic (yes, I know, many are simply playing a role, but I have met enough women IRL who enjoy rough aggressive sex to be certain it's not all of them).
