That could be good, if it did it by removing bad attractions.
Some controversial threads with large numbers of votes were starting to feel like fights that attracted a crowd of onlookers. Those are very engaging, certainly, but it's probably better for both fighters and onlookers to have less of them.
If you're trying to prevent the wrong sorts of attractions, you might also try it on a selective basis. For example, if a thread hasn't received a vote in the past hour or day, or if a user isn't logged in and can't vote, you could continue to display the votes in that thread.
