It's been sorted.
If a submission bypasses moderation when it shouldn't it fails to receive a rating so languishes on '0' and therefore invisible to most people.
If the correct procedure is followed, a moderator will assign an initial rating determined by critical opinion, which is subsequently 'revised' through public ratings being added.
So...the '0' applied was a technical error, and you are quite right....if an admin considered it a '0' [or '1', for that matter] it'd be rejected, not accepted...
