I wonder why there are so many more stories about porn trolls than there are about image trolls? Actually, I guess I know the answer. Media companies use Getty Images and want to maintain good relations with the corporation; the opposite attitude beams from big media regarding those who create, distribute, and/or watch porn. Porn has such a bad name that most people would at least publicly say that anyone associating with pornography deserves fines and/or time in the slammer.
I'd love to see comparison figures on the kind of money porn (c) trolls and image (c) trolls are bringing in. I suspect the image trolls might be extracting more.
