Well, A&D has rules and, as always, no one is above them. It wouldn't matter if the post was two pages long or two words long; if the comment itself doesn't address the artist or the artist's work, it's deleted. Kraider's post could have (and in fact was) transplanted into many other galleries in A&D. Positive or not, it broke the rules.
Just so you know, I did contact Kraider after I deleted his posts (on April 29th) and encouraged him to resubmit a critique.
I will take your comment into consideration and I appreciate your input, so thank you. :)
As stated in the reason for deletion, the kraider's post did not have any substance. The post itself said something to the effect of, "wow these are great!" although I can get you his actual quote if you'd like.
I'm sorry you didn't get a chance to read his comment but, again, it did not comply with A&D's rules. You're more than welcome to PM/VM kraider and ask for a second opinion or show your appreciation. :) I'm sure he'd really like that, actually.
