Easy algorithm to detect bad voters

There is a very easy algorithm for detecting bad voters:

For a given voter:
Let plus_votes = sum of current scores of pictures voted for
Let minus_votes = sum of current scores of pictures voted against
Let vote_quality = (plus_votes - minus_votes) / number of votes cast

A person who is generally in agreement with community consensus would have a positive 'vote_quality' score. Someone voting randomly would be close to zero. Someone intentionally down-voting would risk being in negative territory.
