When looking at the flag tools, I very often see that most questions are flagged as being duplicates of X. I’m often unsure what to do with them, so I usually leave them alone.
But what should be done with them? Usually duplicates should be closed, not flagged – at least that is what I would say given that we have a close reason for duplicates, but no flag reason. Sometimes, when the question is not too old, I might even go to the page, and vote for close to “copy” the flag into the more appropriate close request.
Would that be the correct thing to do? Is there a way to remove the flags then, or should I object the flag after voting close (maybe with a message that I voted for close instead)?
(edit: Same applies to questions being flagged as “not a real question” or “off-topic” where the same close-tag, or even a different one, would make more sense.)
