I came across a question this evening which I thought was unfairly down voted. I instinctively up voted to counter the down vote, however this might not have been the correct way of handling this scenario. After a bit of thought it occurred to me that I probably should have flagged the question for the moderators.
I understand that what I may deem a good question others may not, but there are undoubtedly some circumstances where a down vote has been cast recklessly.
Does one counter the down vote with an up vote, or is the correct way of handling it to flag the down vote for a moderators attention?
