I logged on to SO today to see a 700 point drop in my reputation. It used to be 1918 and now it's 1213. I can't figure out where things changed, and all the "official" calculations don't give me any idea what went wrong. I wasn't getting tons of points from any particular post, so I'm pretty sure its unrelated to someone deleting something. I haven't paid much attention to it, and I know there's a "background function" that checks for specifics, but I haven't done much of anything in the past few days.
Anyone have ideas?
