The thing is though… is it actually CSM according to the law if there is no real child involved along the way? At least some countries might need a law change first before tackling this.
Edit: I checked the local law where I’m located and it’s “images or videos depicting a minor during a sexual act”. I’d argue these AI generated images aren’t of minors because they don’t exist. We probably need new laws first unless it’s provable that the images represent a specific real life minor.
