i fail to see the problem with clearance:

"If a product hasn't had any sales in the last 90 days it's moved into the Clearance section. These products receive an automatic 25% discount and can't be placed "on-sale" by a vendor. This is to help with over crowding in the MarketPlace as well as to try and help spur sales of products that aren't currently selling well. If a product is in the Clearance section for another 60-day period and has not had any sales it will be removed from the MarketPlace. Previous buyers will still be able to download their past purchases of Clearance and Deleted products. In order to re-submit a product that has been deleted from the Clearance section back into the MarketPlace significant changes to the product need to be made as follows:
New Thumbnail and Promo Images
New pricing
Product update or change
*These changes can potentially help the product sell better." *

if a product doesnt sell one copy in nearly half a year - even on sale - it is either a hopelessly niche product, flawed in some way (whether in content or presentation),  overpriced or obsolete.  clearance tries to address these problems.

the bottom line is that Renderosity is a marketplace here to make money.  if your local convenience store had a type of candy bar on the shelf that not one person bought in 6 months, they would remove them from the shelves to make room for something that will sell. 

yes its an intangible item and doesnt take up any physical shelf space, yet that completely unmarketable item is taking up marketplace real estate from an exposure and bandwidth perspective. when someone does a marketplace search or opens up a marketplace category they dont need half the products they see to be ones that havent sold in half a year.

if an aspiring content creator wants a place to upload products where they dont need to meet this absolutely minimal sales requirement i suggest the Freestuff section.
