Except that, in this case, if I am understanding this correctly, all they are "censoring" is material illegal in the US, which Smashwords as a US company can't sell *anyway.* Which makes it nothing more than a face-saving gesture, imho. And this stuff is illegal for a reason: unlike, say, a BDSM fantasy story, which is shocking to prudes but doesn't actually hurt anyone even if it describes unsafe practices, they're only going after books with images of this stuff. And, while you can certainly simulate incest and rape in ways that don't harm any of the people involved, it is impossible to simulate child pornography without harming the children involved. So there is an actual reason for this beyond "Eww! We don't like it!"
