It's kind of rude to do a top five down votes, though. It's like saying "I've found you to be the worst on the site." I mean, don't we diplay people with negative points as '0 points' for a reason? I think that it would just offend people if we display top downvoted. However, I do recignize that it would help to see if someone's downvoting another for the sake of competition rather than their answer quality.
