If you look at the Writer's room or the Chat room, for some reason they don't show up, but if you look at the Forum list which lists all submissions of either kind, there are a few dodgy postings that appear to advertise meds of some sort.

This could become annoying if they figure out how to post in the Writer's room, or in the Chat room...
