I have similar concerns about reviewing products. The Product Review option in our account screens is a decent start. We immediately see a spot to enter our reviews, then wait for approval. But we should be able to at least easily delete the reviews ourselves. As for "backlash" over negative feedback, let's just say I'm trying to figure how to save enough money to buy Shade 7 so I can try creating my own clothing and scenes at least. In the meantime, any merchants who create problems for me won't get any more of my money.
