for now what I see happening is a cycle of "hey, there's no topic on x, let's make one" -> "this x topic just duplicates what's already available, let's delete it" -> "hey, there's no topic on x, let's make one"
@JAtkin, I think those examples should not be deleted - they're better than the other, duplicate ones you linked to. I think the ones you want to delete with your edit should be kept, and the other two deleted instead.
