I've identified this question to be an duplicate of this one. Because the tag does not have many active users, I decided to raise a moderator attention flag (from past experience, I learned that my own close vote will rarely result in the question to be closed).
The flag was deemed
helpful, but the question is still not closed.
- Did a non-diamond moderator review the flag? This post suggests that the flag can also be handled by 10k users.
- If the duplicate reason is obvious, is it allowed to raise another flag?
In this particular case, the immediately OP agreed that the question is a duplicate. Would another flag be justified here?
