Now the issue I think lies when people are just spamming out 10 posts a day with a single image in each of them.

I think that's fairly key, right there. One of the users @patrice's crew is currently taking on posts approximately 300 memes a day... what's that good for?

I absolutely enjoy earning rewards as much as the next person, but I don't sit around and mircomanage "how am I going to make the most from the next post." I just create something and hope it will be interesting and/or engaging to people, launch it and hope someone finds it interesting.
