Re: Interesting questions
Now, if someone sold a magazine with a picture (presumably compromising) of a minor, would they not be prosecuted?
Yes, but a magazine involves a conscious editorial decision by the staff.
Facebook cannot manually vet every image and video as they are uploaded, so as long as they respond quickly on the first report, then I would say fair play.
What they can do though is compare images on upload against their blacklist of stuff which has been reported and removed to prevent re-upload. I would say they are liable for not making their take-downs stick.
That said, if the image is flipped, cropped, resized or otherwise tweaked, it can be genuinely difficult to compare against a previously removed image and some material will unfortunately slip through.
