I don't think the reputation check is the problem. The problem is that the promotion rule basically says "all Registered Users > 3 days and >= 0 posts" which is pretty much all users. The problem is that there's no way to say "exactly 0 posts" or "<= 0 posts". You can of course add another rule to promote back to registered users if they have one post, but once they are there, they'll match the original rule again.
