Not to start any sort of argument or something but generally it's preferred that you don't voice complaints about DD selection on the artist's work. So, you're better off not doing this or otherwise you might get in a bit of trouble with the admin. Just a warning.
I'm just getting the impression that GDs might be cracking down on complaints (if not now, then in the future) because a lot of them seem rather aggravated about it. So it's best to avoid complaining on the DD's or to the gallery directors.
