Now see how many people can write a description of a way to discern the difference between the two using just the image. I hesitate to say it but experience suggests this probably is 'porn' for some sick person.
It's made to be porn by the context it's viewed in and by the reaction of the viewers - some people, I gather, are turned on by car crashes.
It's a harder problem than your comment seems to be suggesting.
Personally I think a blanket ban on images of full-frontal nudity of a person would be reasonable for both a public forum like Facebook and a newspaper.
It's extremely difficult for a human to discern the difference let alone computers which for all the ML are still profoundly stupid.
To quote Justice Stewart in Jacobellis vs. Ohio:
I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description ["hard-core pornography"], and perhaps I could never succeed in intelligibly doing so. But I know it when I see it, and the motion picture involved in this case is not that.
