Occasionally, a user will cast a close-as-duplicate vote that's clearly incorrect. If that vote closes the question as duplicate, a gold tag badge user in a tag for the question ("dupehammer user") can then, as I understand it, unilaterally reopen it (thus overriding all the previous votes).
My question is about what happens in cases where the incorrect close vote does not close the post. In such a situation, a dupehammer wielder can close and reopen the post in order to clear the close votes on the question. This is clearly somewhat abusive if there are no close-as-duplicate votes, but in the case where all the close votes on the post are close-as-duplicate, doing this at least somewhat seems to tie into the dupehammer's regular functionality.
My question is not really about whether/when I can do this, but rather, when I should; under what circumstances should I as a dupehammer holder close and reopen a post in order to clear incorrect duplicate votes from it? Given that this is a fairly hidden feature at the moment, there's no obvious guidance for the circumstances under which I should use it.
In particular, is it my "duty" as a dupehammer user to clean up incorrect duplicate votes? Or the opposite: should I stay out of using the dupehammer to mess with vote totals, and only use it when the post is actually incorrectly open or closed? Or is the answer somewhere in between?
