Last I night I downvoted a guy's answer because I thought it was wrong and I commented why I thought it was wrong. The guy threatened to report me for "unnecessary down voting". Could I really be punished for what I did or was he just trying to intimidate me into undoing the down vote? Here is the post if you want to see it. https://stackoverflow.com/questions/14000623/php-upload-issue-with-array/14000656#comment19327519_14000656

Your votes are yours. The asker didn't like getting downvoted and threatened to report you.
There is no one to report to, however.
There is an algorithm that detects serial downvoting, but unless you have been doing that, you have nothing to worry about.
