I personaly have no problem with fanart as long 
as the artist signs the piece so it can never be 
mistaken for the real production cel. I don't 
think it will have a "bugs butt" effect with the 
value of my original production cel if it is 
copied. If they are listing them to auctions they 
should make it VERY clear what the item is in the 
title, NO click on it to see! People harassing 
people is wrong! I would like to think that this 
forum is a place to learn how to know the 
difference and all could be a part. A Newbie 
should aways welcome. JMHO
