I'm new to photo.se, but have been around other SE sites for a while. I just wanted to check whether I'm actually doing the right thing and it was just a mis-click, or if there's a bit of a different protocol 'round these parts I haven't yet familiarized myself with

I flagged this post:

How to recreate the perspective and field of view of an existing photo?

As a duplicate of this:

It is now closed as duplicate, but my flag was declined. If the decline was a simple mis-click of the button, I won't give it a second thought.

Is there something else I'm not aware of?
