I mean reward correction is understandable ... But I think it's important to atleast take the time to tell the author about why they have down voted ....
In most cases the author feels "sad" because they think that there is something "wrong" with their post.
I can't do this for other front ends but the only thing I can do, would be to add a "reason for downvote" for Terrive ( when I add a down vote option ) but I don't think it would make much difference because I only have a few users and no down votes on any posts so far.
That’s good you have no downvote there
And I do agree if people had to leave a comment when downvoting at least then people would know why
