I'm certainly not pissed at your for having a 
completely different view of the situation from 
me ^^ I've had people use cropped versions of my 
cels on their image galleries, and as their 
avatars, and frankly that kind of image 
appropriation doesn't really bother me. It would 
be polite if they asked, but very few people do 
so and I'm not out to change the world. 

My real problem is when people create fancels 
from good scans without markings to distinguish 
them as fancels - I've discovered two cels of a 
character, one an extremely good copy and the 
other the original. The problem? I don't know 
which is which! They changed hands so many times 
over the years that it's almost impossible to 
tell, and no one remembered anymore. For this 
reason I discourage copies being made of my cels 
with stamping and smaller image sizes, as well 
as cropping off paint edges. I don't want 
someone to be staring at two cels 
going ... "which is the original?" The original 
creator may have been nice and said it was a 
copy, but who knows what future owners will say 
or do? That's just my piece, based on a personal 
experience.

That's my viewpoint, and I'm happy to hold it 
peacefully in this community ^^
