The stars feature has been a bone of contention due to the obvious
issues you have discovered.
If we ever get a upgraded version we will be migrating away from the stars to something like a thanks feature.
I have never tried it but doing some database diving I guess you could reset it somewhat. But you would need access to the database tables.
