So today I was awarded upwards of 200 points from previous posts within about an hour, so I figured glitch. And sure enough, points were removed. Anyone know what the heck is going on?
Sounds like someone went vote-happy on you and the votes got cleared out by the voting fraud detection script.
It's unfortunate when that happens for legitimate upvotes, but it also serves a valuable purpose of removing similarly cast downvotes or upvotes cast to artificially inflate someone's reputation.
