In all my time here I have only asked once to have a comment removed from one of my images. It was a blatant troll. To me that sort of removal is legitimate. I think the problem comes in that people are not always aware of what makes a good constructive crit and what is a sdtatement of personal opinion in terms of likes/dislikes.

Pass no temptation lightly by, for one never knows when it may pass again!
