I absolutely agree with this opinion. Putting 
aside all the copyright and ownership 
rights/laws, what does it matter if someone 
takes your scans and posts them on their 
websites. If they do not have your watermark and 
even assuming these people say they own that 
cel, what does it matter? If I put on my website 
that I have a Van Goughs Sunflowers hanging on 
my wall, would you believe me? And would the 
real owners of the painting come and sue me? I 
mean really do you buy/collect your cells so 
that you can say to others "I have it you dont" 
and make others jealous of you? Or do you 
collect cells for your own pleasure and 
satisfaction?
And if they still have your watermark on them 
isnt it just flattery and a good advertisement 
for your collection?
