Friend of mine, got upvoted for one of his nice answer and got downvoted for same answer by someone without any reason. Even reason for downvote is also not mentioned in comment.
It is assumed that low quality answer or answer with lots of mistakes can get downvoted without reasons, but this was really good answer.
Is there any way to get this down-vote reviewed by moderator as this is real bad experience to have down vote on good answer without proper/silly reason.
Reference is here
