I had flagged 3 comments that were posted under my question here. The comments were absolutely not related to my question.
The flags were rejected. But then the same comments were deleted some time later by a moderator himself. (I can say that the comments were not self deleted because the user's last activity was some 6 hrs ago and the deletion of comments occurred around 3 hrs ago).
I want to know the reason as to why this has happened.
