Lets be honest there would be very few people here who would not want some revenue if it was available. Two tier systems would not work. I would assume that most people who post here think there work is of a standard that others would like to use it. Some people might be more desperate for money than others. We don't know the circumstances of everyone. I do know there are some people here who really really do need the money they were getting from here.
Let us also be honest. The site earns money because we and other people access it. And because we and other people upload items here. If that didn't happen there would not be any money.
