the problem happens when people don't see any criticism as constructive. than anything's trolling by them. i do enjoy it when someone feels the need to snap at me over a comment though. it means i made them think a bit!
it helps that i've given up on any hope that people will take my remarks in a positive light.
I've noticed sprite comickers(namely on smackjeeves) tend to be the most vicious to other comickers. It's either they don't understand the effort people put into real drawings that aren't copy/pasted onto the page or they're just attention whores trying to get it else where.
