Part of the problem is that everything that happens on the internet is classed as speech or expression. So if there are any government attempts to regulate it, there are howls from the libertarian right but also certain quarters of the left that this is the evil government taking away our rights to..er...watch women being abused or book prostitutes. The online world is somehow exempt from all the normal rules that everyone accepts in the offline world. For instance, if I argued that sex traffickers should be allowed to advertise in shop windows, then I'd be judged insane. But if they're advertising online then this is seen as almost reasonable, and any attempt to stop them viewed as an act of Chinese style state totalitarianism.
But then, sexual 'freedom' has always been a fetish of the left. While they are quick to condemn any other predatory capitalist industry, the sex industry is always exempt, because everyone (men, mainly) is free to express their desires as they wish, and turn sex to profit where possible. You can just imagine all these hip, Californian, NYT reading techies who are oh so liberal unless anyone wants to stop women and children being abused and therefore deprive them of all the millions they're making from all the clicks it drums up.
Can't say I agree with much of what Dworkin wrote, but she was right to say:
The new pornography is left-wing; and the new pornography is a vast graveyard where the Left has gone to die. The Left cannot have its whores and its politics too.
