But a lot of those "casual exhibitionists" are unverified. Many of the photos may have been taken with consent, but are distributed without. Sometimes that's revenge porn, sometimes it's hacked/jacked content, etc. Distribution of questionably sourced content can be quite damaging to the subjects.
If the "casual exhibitionist" is harmed here, it's dwarfed by the harm already being done to subjects without consent. And there are still plenty of suitable venues out there. Including verification with pornhub.
If you look at the actual mechanisms by which harm happens in a revenge porn case, I think you'll find it isn't dependant on pornhub at all.
What do you think are the mechanisms by which revenge porn harms?
If there is a legal case to be made against Pornhub, then the authorities should make it. Otherwise they would do better to go after those who made (or uploaded) the offending material in the first place.
And spinning up a new video host (that you intend to make money somehow) isn't cheap or easy.
Is it still a thing? What malware can a pornsite contain that cannot be uploaded to or linked to from a regular smaller niche or bigger broader site? Do you download and run hotgirls.exe dialers or what?
Nor is it terribly safe right now legally speaking. Considering the child porn castoffs from pornhub will be out looking for a new place to upload their trash. Eventually, not only child pornographers, but so many other undesirables are on your site, that it's just dangerous to continue running it from a liability perspective.
I suspect you're getting a lot of downvotes for this.
I don't know how one's life could get destroyed just by uploading a sex tape to a porn website. It's more the sending it to friends and aquaintances that causes hurt (and for the vast vast majority this would hardly "destroy their lives", very few people are that fragile), which can be accomplished easily enough without the porn website.
You people have zero empathy provided you get your porn.
You don't think that a victim of revenge porn feels like being raped everytime a stranger jerks off on her intimate image/video uploaded without her consent and it doesn't take a toll on her psyche thus destroying her life? Then shame on you.
Which could well be a net negative (I'm assuming both the viewers and exhibitionists get something out of it) given how small the positives are.
