I have run in to this twice today. As I was typing a answer Random closed this and this question.
For the first one, I understand that that one is truly a duplicate (even the poster said so in the post) but the reason it was a duplicate is that the original question was closed (and I think it should not have, at the very most it should have been migrated to SO). Random just pointed to the original question but nothing can be done with the original question as it is closed, he either should have not done the duplicate or should have re-opened the original question.
For the second question the question specifically asks, can I do anything about this without buying a UPS, and random redirects the question where basically all of the answers are "get a UPS" I actually had some good information for him about troubleshooting the power in his house that would not be relevant at all in the "duplicate question".
Questions that are deemed sufficiently off-topic may be closed by the community. Users with 3000 reputation can cast up to 24 close votes per day. When a question reaches 5 close votes, it is marked as closed, and will no longer accept answers. Closed questions may be opened by casting reopen votes in the same manner. However, you can only vote to close or reopen a question once.If I was a brand new user with 1 rep that does not, to me, say "Go edit your question and it may be reopened", it just says, "you may get lucky and it could get reopened" I would not know I could edit.
