Every once in a while, I stumble upon an old (usually subjective) question that would have been closed before it left the front page if it was asked right now.
I've earned the privilege to vote to close, so I can't flag the question as not constructive or similar. Therefore, I've been flagging them for moderator attention.
As far as I can tell, these are my options:
That would work probably work and it would require the assistance of only four other community members (rather than a moderator), but it seems sub-optimal.
Vote to close. Since the questions are quite old (some were asked in 2008), that doesn't seem to have any effect.
I have read How to get attention required to close old posts?, which is status-completed. It made me think that voting to close a question makes it appear in some list, but it looks like I misunderstood something. I have tried voting to close a few old questions, but none received any close votes besides mine. It's possible that there simply was nobody that agreed with me, but I find that hard to believe.
These are the questions I recently voted to close:
Flag for moderator attention. This is what I have been doing so far and all my flags have been declared helpful and all the questions have been closed.
I'm just worried that this takes up the moderators' valuable time. Closing old questions cleans up Stack Overflow, but I imagine that there are more important issues.
Is flagging to close old questions best practice or is there a better way to deal with them?
