I'm talking about this question: Avoid developers to see included plain text code..
It was marked as duplicated, while in the comments we can clearly see it's not a duplicate. So the users with the 'power' to close questions overlooked at it and decided it was a dup. He's not looking for obfuscation, he was looking for something else. I had some sort of answer but the answers were closed.
Did I act correctly? I don't have enough rep as to reopen the question, but I thought I had an actual answer so I tried to answer in the comments, which I know it's a bad practice.
End result: the user was happy and I answer the question. My question is, how to avoid this situation in the future?. I edited the title and said in the edit note that it was not a dup, although nothing happened. It was incorrectly marked as a duplicate, and while I had an answer for a correct question, I couldn't answer properly.
What is recommended in this case? I think allowing to tag the people that closed the question in the comments would be a good idea.
