Recently I'm seeing answers from new users, that don't add anything to the discussion. That is, some answers have already been posted, and the new answer says only what has been said before, without even elaborating on it like earlier posters have done. My impression is those users have not read any of the other answers before posting their own.
What should be done about such answers? My intuition has been to flag them as "low quality", but then I see those flags disputed. When I myself see such answers in the "low quality" queue, I want to recommend deletion, but among the reasons provided there's no "this answer has already been given by someone else".
What then is our stance on such answers? Do we just tolerate them and do not upvote them? Or can we perhaps add an appropriate reason to "recommend deletion" from the "low quality" review queue?
