Specifically, when a post is flagged as in need of moderator intervention what does it mean?
A while ago, this happened:
I asked a question which was related to a question supplied in the comments but did not answer me. Following that, I received a private feedback to review if that answers my questions or not. Obviously, I clicked on no and pressed submit. Also notified the user who marked it as duplicate and edited the question to make it look pointed towards the author's intent(me). After a few hours, I saw my post taken down as a [duplicate] and Comments on the post deleted?. Upon flagging the post for moderator intervention, it was declined with the above message. No custom comments were put as well.
This of course looks like a custom message, but was my flag a standard one?
I have read the thread What are acceptable reasons for flagging as "Requires Moderator attention"?
but unfortunately it's a continuation to : Is "Please Vote to Close" a valid use for Flag - Requires Moderation Attention
and has answers which genuinely could not address what I have asked.
