This poster thought he or she was doing other 
collectors a favor.  If I was interested in cels 
from this anime, I'd have been quite happy to hear 
about the auction.

That's not to say that I don't get an evil, self 
satisfied thrill when I find an auction that 
nobody else has noticed and practically steal a 
yummy new cel, but ripping into this poster for 
trying to be helpful is rather rude.

A gentle request would have been just as effective 
as anonymous anger, if not more so.

Let's keep the hobby civilized, please.
