It’s not trolling it’s bullying. You need to think beyond this being about “porn”. This is a reputational attack that makes the victim more likely to be further victimised via date rape, stalking, murder. These things already happen based on rumours, deepfakes images/videos will only make it worse. The other problem is that it’s almost impossible to erase once it’s on the internet, so the victim will likely never be free of the trauma or danger as the images/videos resurface.
