And is that OK? I mean I get it, free speech, but just because congress can't stop you from expressing something doesn't mean you actually should do it. It's basically bullying.
Imagine you meet someone you really like at a party, they like you too and look you up on a social network... and find galleries of hardcore porn with you as the star. Only you're not a porn star, those galleries were created by someone who specifically wanted to hurt you.
AI porn without consent is clearly illegal in almost every country in the world, and the ones where it's not illegal yet it will be illegal soon. The 1st amendment will be a stumbling block, but it's not an impenetrable wall - congress can pass laws that limit speech in certain edge cases, and this will be one of them.
