I got a heap of strange undownvotes yesterday:
I'm wondering how this was possible. Were the downvotes not too old to be revoked?
The original downvotes that were cancelled don't show up anywhere in my list (I went back a month or so), and neither of the posts had seen a recent edit that would have allowed the user to change his vote.
How was the voter able to undo votes this old?
Or is this evidence of a removed user account? Do cancelled downvotes not show the
user was removed message that you see when *up*votes get cancelled?
