My 4 year old question was flagged as a duplicate of this 4 month old question by the same user who posted that question. My question has more upvotes on both the question and the answer, and is (obviously) significantly older. I also happen to think they aren't even the same question--the other question is a much more specific case that most users wouldn't need. It seems to me like a silly attempt by that user to drive more traffic to their own question.
I can't flag the flag itself for review, so what's the proper response to these sorts of cases? Just flag for reopening? Try to get a moderator involved?
