Not a rant, just curiosity :)
In this question from Jan 2013, I answered normally (not my best answer ever, but still worth reading I guess, and it gained one upvote).
Another answer was marked as accepted. Nothing strange then.
Except for the fact that today, the user who has written the accepted answer edited both the question and the answers (all the edits was a one-character "fake" edit), and removed the upvote from my answer.
No downvote, just upvote removal... that is strange, because when someone really doesn't like an answer, usually he/she downvotes it. Amazed by this curious gravedigging, I've run the Have We Met? query on SEDE, and the result was that we never met. I don't really care when I got some random downvote, but this "upvote-removal" has been so weird that led me to ask this question:
Is fake-editing other answers / questions to be able to alter the vote casted to them legit? Should this kind of behavior be flagged for Moderator attention?
As a side-question: any clue on what happened? I know I can ask him, and I probably will, but I'm more interested in your (hopefully) funny comments right now...
