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
Note: I think if down-voting is not reviewed because it is personal opinion then it will play big role in case of bounty award question. Please explain.
Another example is here.
Why downvoting should be reviewed if applied for review?
Newcomers coming across the community sometimes get offended due to getting down-votes with no explanation or with no valid reason. Community sometimes trust person by their experience of rewards got (reputations & badges) only.
To grow community with active users, it can be possible to provide such a thing under revision of higher privileged users. Also we can define some rules so that we can reduce 'downvote reviews' less in numbers. (e.g. downvote review can be applied once per week if no comments on downvote present). Of course, there is lot of things that can be build on this, like we had designed review audit (one of smart mechanism).
