I usually end up checking whether an artist is DNP or not by running a search with their artist tag, and if there's no results, then following up on the actual list. The list is also kinda hidden-- from the upload page, there's no direct link to it, and you have to click around a bit to find it. What if we were to have an image that just said "Artist is DNP," visible from the thumbnail, and tag every DNP artist with it? That way, if you ran a search on an artist, you could tell the difference between an artist who doesn't have any postings and an artist on the DNP list.
Maybe it's dumb, but it seems like it'd make it easier to see who is and isn't on the list.
