You're an admin of a large Facebook group for selling used goods. How can you set up admin assist (or any other tool) such that the selling posts without photos are automatically rejected, and their authors are temporarily blocked (say, for a month) with a notice on what they've done wrong? Discussion posts, on the contrary, can stay without photos.
Background: Your group receives too much attention, and so far you couldn't find any co-admin or moderator who would do proper daily cleanup of posts and members. You wish to partially automate removing (or keeping away) junk or useless posts.
