Find out who downvoted your StackOverflow answer.
This script will check if you have an answer on the current page, if so, it will check the reputation of every other user who posted an answer or comment on the page every n seconds and if your vote has gone down it will tell you the name of any users who's reputation has gone down since the vote.
This works because it costs 1 reputation to downvote on S.O.
You must be logged into S.O. and viewing the page during the downvote in order for the script to catch it.
