For a couple of weeks, Deviantart has been randomly telling group admins the wrong folder to which you are submitting your art to. Because of this, a few submissions have been denied incorrectly. Admins are asked to now check the submission itself before outright denying it, but if you feel that your submission was incorrectly denied, please comment on the notification you get.
The following rule has been more or less an unwritten (and sometimes unenforced) one for a while and for different reasons, however, it now needs to be explicitly stated:
NSFW models, whose use in imagery would break DA rules, will not be accepted into the group in any form or fashion. They may be able to take advantage of a loophole in the site's rules for your own gallery, but they could never legitimately be used in art submissions to DA. Thus, there is no benefit to the group as a whole for us to promote the models in our gallery folders.
This applies only to models whose imagery would break the DA rules. So, genitals or sex toys meant to look like their "realistic" counterparts are pretty much what we are talking about.
The point has been made that female models have been accepted before, however, that was a fallacy of the accepter of the submission and the lack of clear rules. That submission has been removed from the gallery folders following this decision. This has nothing to do with personal opinion, something I find to be a precursor to corruption, but rather with the continuity of the group. Taking advantage of a loop hole (or accidentally accepting rule-breaking images) is not a good way for this group to stay on DA's good side.
