Some very insightful comments.
On the issue of regulation, the problem is now the hubs. While much of the overtly illegal material has migrated to the dark web, the hubs are completely out of control. Internet porn interfaces are now more akin to open platforms like Youtube, which means they are therefore in effect completely unpoliceable. As far as I am aware, any user can upload anything they like to the hub sites within broad parameters. And even then illegal material is not immediately taken down.
Action must be taken, but the question is what? The platform economy is designed to resist any form of regulatory intervention. Furthermore these sites transcend national jurisdictions so there is the question of what body of law should be brought to bear on them.
A feminists analysis is obviously warranted here, because pornography does for the most part deal in misogynist tropes of female abuse and submission as well as other deviant themes such as incest. Pseudo-paaedophiliac imagery of women made out to look much younger than they are is becoming a frightening norm too.
However, male oppression is only one dimension to the porn problem.
As Beach says:
"As Dines and Jensen say, the porn industry has hijacked our children's (and many adults') sexuality. The porn industry is a parasite. They want young boys exposed to pornography because it has an addictive element (the orgasm is an extremely powerful social conditioning tool) and they want their sexuality to be fucked up to the point that porn is the thing that gets them off. It works just like cigarettes, the younger the exposure the better."
Porn is addictive, and while many men who consume it are overtly contemptuous of women, some will be poorly socialised and become reliant on it in the absence of the capacity to form a relationship. In short it will attract sexist men, but also very vulnerable men and children. Though as Beach also says, it will condition males into accepting a misogynist narrative of sexual relations, so the net result is the perpetuation of sexism in our society.
Furthermore, women can be consumers of pornography and porn, and they are increasingly representative of porn addicts. More research is needed on this.
This woman's experience is interesting:

Pornography is a massive public health problem - one that is for the most part ignored by government. Why, I am not sure. Possibly because porn probably accounts for a sizeable slither of GDP. Every once in a while a politician will suggest some modest regulation, it gets shouted down and then nothing comes of it.
