PLEASE NO ARTWORK IF IT IS NOT ACCOMPANIED BY A STORY! There are plenty of other groups dedicated to artwork! We're sorry, but we'd like this to be dedicated to literature!
Well I had a problem with this before and how I solved it is by having submissions only be submitted in an unsorted file which also requires votes. Then trusted admins can have a second look at the submissions before it is moved into its respective folders. The drawback is having the submissions really tightened down almost to a halt and more work for admins to do but it made my group more clean and niche!
