Someone abuses a child, film it, put it in AI. And they now have that child's model.
Throw away the child and they're currently guilty free if any charges. Of course that won't be enough so repeat the process.
It's not like someone is creating a model in blender and than running that though a AI. Not like that doesn't happen anyway.
Those who seek sexual gratification from the abuse of a minor. The real deal.
And those who are aroused by the body of the minor, or watching the abuse of an minor.
If the model is "good enough" than you could potentially say that those who are interested in pedophilia probably won't seek the further extremes to fulfil their pleasure.
However, in the long run they are still pedophillac and the real deal will always be the more for those.
