I was looking at this off-topic posting. Hovering over the "delete" link offered me the chance to "vote to delete".
Since I concurred with the consensus that it was essentially a duplicate of another question, I wanted to vote in favour.
Did my vote happen to be the one that pushed the vote-count over the necessary limit, or is there some instant-delete privilege I am unaware of? If the former, then what's the limit, please? If the latter, then the hover-prompt was misleading.
(I imagine there's some FAQ that says all this but I could not find it on a cursory search).
