I'm familiar with points, upvotes, downvotes, etc. It's not very interesting, but it's understandable. However, I recently got some points deducted for an "unupvote".
I don't mind; points are not fungible. But I don't understand the term. My best guess is that somebody who had upvoted has changed their mind and downvoted. That makes sense.
However, every time this has happened to me, it's been accompanied by more upvotes, so I'm sort of unclear what's going on. Is this a reaction, like the reaction to serial downvoting?
