We've been having a problem here. A lot of people have been resubmitting things that were rejected. Multiple people, multiple times, for the same pieces.
When you submit something to a group, it generates a message telling you if it's still pending or not. I'm pretty sure it goes away on its own when something is declined, I really don't remember, but if you keep it in your messages until something happens you might remember not to submit it to this group five to ten times.
Or find some other method.
Doing it once or twice is understandable because people forget things, but I've seen some people submit the same exact picture(s) several times for over the course of a month or longer
. I can't really think of a way to say this personally without sounding rude, haha.
