Banning diffusion models doesn't work, the tech is already out there and you can't put it back in the box. Fake nudes used to be done with PhotoShop, the current generative AI models only makes them faster to make.
This can only be stopped on the distribution side, and any new laws should focus on that.
But the silver lining of this whole thing is that nude scandals for celebs aren't really possible any more if you can just say it's probably a deepfake.
