Re: It's simpler than that
One of the problems is that pictures of nude or seminude children is very different from country to country.
Sally Mann's "Immediate Family" (Wikipedia link) springs to mind.
Publishing 13 nude photos (of 65 in the collection) of her kids was controversial in 1992. In her case the argument is more over the ethics of publishing photos of her kids in that fashion and them growing up with intimate childhood photos in public circulation, in the same way there are concerns about parents oversharing their kid's lives on social media these days.
But it certainly wasn't pornographic, nor depicting abuse. But it would be a stonkingly sophisticated AI that could make such distinctions.
