FYI, last year a beautiful BBC Sherlock fanart was one the best sellers too. That raises a few questions, because we now even have a proof, one of them being: what's the point of NO Fanart Prints policy when it's obviously not being followed/selectively followed by the site itself and there are proofs of fanart prints being sold?
From FAQ #743: "You may be seeing Fan Art available as prints that are clearly violations. Please note that images submitted through standard print accounts are not checked by our quality control staff until someone orders the print. At this time, the images that violate the prints guidelines (found in the FAQ) will be rejected."
Yeah, we see how they are rejected, dozens and dozens of them I've seen definitely being sold for years.
Fanart does not stop being fanart when miscategorized to enable Prints. (+ many of them give hints it's a fanart from their title, the description and the work itself, for those who can recognize what it is, so there is no "we didn't know/overlooked it" that can used as excuse)
I love and need dA more than I can describe, but this been bugging me for years, it just isn't right. If policy isn't followed by many artists because the don't know it/don't care/are just using the opportunity because they can (they just want to earn some money with their art), the site at least should and not allow selected (big) number of fanart and celebrity Prints which are definitely being sold because that is not fair to the rest of the community, among other reasons. What just wrote might cost me a ban after 6 years of being here if someone doesn't like me "exposing" dA, but this had to go out. It would be wonderful to get some long awaited explanations and acceptable excuses for this, or even better: let us all sell fanart!
But that will never happen.
Btw, congrats Best Sellers! Gorgeous works and well deserved!
