With respect to this question (and its implemented answer), is it possible to increase the reputation penalty for users that down vote a question without leaving a comment?
The reason I'm asking is because I'm seeing an increasing number of perfectly good questions being down voted, which in my opinion is happening because the voter doesn't like where the question is leading, usually because the OP doesn't fully understand what they are trying to achieve. I don't see this as a valid reason for down voting.
Maybe as well as an increased penalty for down voting without leaving a comment, if other people up vote the question, the penalty could be weighted even higher?
It's difficult to offer a list of examples, because this is a trend that has been spotted over a period of time, but I can easily offer these examples from my comment history.
Finding out what user Apache is running as? (has since been upvoted)
Where can I find iPad Sample Code (has since been upvoted)
Maybe an alternative would be to impose a heavier reputation penalty on a user that down votes a question when the number of up votes out weighs the total number of down votes by a designated factor.
It's always nice (or polite) to get a comment explaining why question has been down voted, but I believe we should be attempting to discourage down voting, especially when it isn't justified.
