High rep users can see the last comment there.
Is it mandatory on this site to provide citation? Last I checked, I have seen lots of high quality answers without any citation. Also, there are lots of wrong answers which provide proper citation.
Talking about for the sake of answerer, that user has 1 reputation. I don't think downvotes would hurt him.
Should Diamond Moderators use their diamond powers after judging the answer's correctness?
