Over the time, about 10% of your assets will have at least on sale, of those 10%, again 10% will have multiple sales (that numbers will get higher, the longer you are a contributor).

You have several assets in your account that are erroneous:

(obviously, I did not have the full-size assets at my disposal, but if I see issues here, I won't buy. I would report the assets to Adobe, and they will check and remove them, which will hurt your sales more, as they will place your search results at a very low relevance, if they won't block your account.)
