It's fairly easy for an admin to check a specific individual's rating history....and alarm bells tend to ring when you find a large number of works say, rated 7, 8 or 9 as averages, when the individual's ratings are all '1'...it means the consensus is at odds with the individual and one asks 'why?'.
If a work has 10 ratings, all 'high' except for one....that's odd.
If two works are in that boat....that's suspicious.
If all an artist's works are so...then questions are raised about whether it's taste or vindictiveness on the part of the rater.
As for 'losing' ratings after the crash, one of mine went from 10 to 6 [sniff].....but life goes on...
