This is relevant to the question What is serial voting and how does it affect me?.
I had the same thing happen to me yesterday, as six of my answers were downvoted at the same time. According to the answers provided to the question above, I should get the reputation back.
However, it seems that while some of my reputation was returned, not all of it has been. (basically half of the lost reputation)
Can I do anything about this?
undownvote
and reputation is given back. Thanks!!
