I just noticed that this answer is a nearly verbatim copy of my answer to the duplicate question here (I answered before I marked the question as a dupe: I'm not sure what happened, but I might have answered before I found the dupe).
This seems to have been done in good faith (it links to my question), and I can imagine it was copied with the intent of giving it greater visibility to people who got to the first question, but it seems wrong somehow (this meta question suggests it is, anyway).
What's the appropriate way to proceed here? Flag for deletion?
