Attacked by Downvotes; what do I do?
So, I've experienced my first down-vote attack. For some reason, a user is going through my recent answers and down-voting all of them. He/she has down-voted 9 of my recent answers in the last 3 minutes. Obviously, they couldn't have read all those answers in three minutes. Also, they were great answers :)
Can anything be done to prevent such behavior? Can anything be done to challenge a down-vote attack?
Additional Info: I rarely down-vote. I can't imagine this is a "revenge" down-vote attack.
