We all know that there are tons of pictures waiting to be approved or rejected and take their place to be sold. I have a simple suggestion for the review line.
Wouldn't be nice, if contributors with higher approval ratio have faster review times. Because they are already picky and choose the best ones to upload.
Such a priority will push uploaders to be more picky and have a greater approval ratio, hence higher quality will be obtained. The approval ratio already effects the weekly upload limit, but many contributors are not even close that weekly limit.
We consider all contributors to be created equal. It may be that you have done a mistake in the beginning and your approval ratio stuck with you. Better approval ratios bring a lot of advantages but we consider the current review scheme to be the best and fairest to all contributors.
