@operaguy As long as there can be workable appeal to independent human judgement there would be less a problem. It would be the only available option I think. People spend time and effort on making a good upload. The publisher earns money from that uploaded content, so they are expected to do something in return. If an image is not accepted, the least one can expect is being told why it is not accepted. The site needs user content to dilute the ads with. It is the main ingredient of their product, and be prepared to pay the cost.
