There seems to be posts daily about "revenge down-voting" and I feel embarrassed to be adding another, but as with the other users it is something that I find frustrating.
I understand that the appropriate action to take is to flag questions when you have suspicions and let the moderators take appropriate action. I recently did this and unfortunately no down votes were rolled back (not a massive issue as the rep is easily gained back) however more frustratingly two days later I have received another batch of down votes.
Although I will wait before reporting this new possible spate of down votes (this is not what this question is about), I feel a little blind about what is going on with my previous question flag as it was marked only as "helpful".
Therefore I wonder if it would be appropriate for moderators to leave brief feedback about what action was taken (possibly in the form of a comment - such as "warning sent") and even who the anonymous serial down voter was?
