Would it not be better to have a voting system where you HAVE to leave a review, I know that would open to abuse but it would be easy to see who's being an idiot and remove them. What's the use in a score system if you have no idea why people are voting the way they do. It's no good to me to know whether people like it or dislike something without knowing why. And surely there must be a way to deal with zero voters? like kicking them in the face repeatedly?
