I came across this question which seemed interesting but was already marked as duplicate by a single user with a gold tag badge rather than being voted as a duplicate by consensus. I took a look at the already-answered link and couldn't find a good answer to the question; in fact it seemed to only answer a variant of the question specifically called out as not what the original asker was looking for. I couldn't find any other questions on SO that did answer the question, so I voted to reopen the question.
I wanted to go a bit further though because the question was (IMO erroneously) closed by a single user rather than a consensus of 5 voters, so I checked on meta and found this question about reopening duplicates. The accepted answer indicates "If you believe it is not a dupe & have a strong opinion on that, just flag the question with specific details." so that's what I did, indicating that the linked question didn't answer the original question. Today, however, that flag was declined with the message "flags should only be used to make moderators aware of content that requires their intervention".
So what is the right path for this kind of thing? Should I just leave my reopen vote there and hope it gets enough other votes to reopen? My main concern with that appriach is that this kind of question is very domain-specific and not likely to get a lot of views. For voted-diplicate questions that's fine since there were clearly enough views to get 5 close votes, so there should be enough to reopen if appropriate. But when a question is closed by a single user, it's not guaranteed to get enough visibility to get 5 reopen votes if that person made a mistake.
