Encouraging people to explain down-votes
Suddenly, I noticed I am getting downvotes on my questions that were asked many months back!
And few days back my reputation was rolled back stating that someone has upvoted me! I would like to say, if this is the case, you should take a precautionary action like
If someone downvotes, he should give a mandatory comment on that. And if other accept the comment then the downvote should be done.
Same with the upvote.
Waiting for your response on this.
I changed my name and pic due to this down votes, now after a month, I restored my name and pic, and suddenly got 3 downvotes on some past question, see the image.
