The problem is, the things we wish to make vendors aware of in making their work simply are NOT being checked for in most stores. I know for a fact they are not. I have been a store tester here. Let me show you what I mean. Look at the attached illustration. Both models in this render would be accepted into the store of Renderosity. However the one on the left bears a rendering artefact outlined in red. Both models however would not be accepted into the store at Daz. Only the one on the right, with the blue outline would be accepted, since it has co-planered edges along the bottom that are not showing a false shadow. Now granted, this is only one example of quality. There are many other examples we hope to give in time, but someone has to start somewhere, so I am starting with this one ;)
