> It works sometimes however. My comment [1] was controversial and was moving up and down between negative and +4 votes for the first two hours of its life. After I made the edit complaining about the downvotes, it started rising rapidly and is now resting at +22. Downvotes are also disabled after a period of time. A comment can only go up or maintain its rank once that has happened. This is evident when reading older threads. That probably doesn’t account for all of the upvotes in your example, of course.
