Some of my reputation data on MathOverflow got changed in a past couple of days back and forth twice. In particular, my reputation went up 200 points, then back to the previous state, then up by 160 points, then again to the original state. Any explanation? (I have not a clue of what's going on).
I apologize if there were similar questions posted in the past weak (or two?). Then let me see a link, please.
