A guy at my work upvoted a bunch of my StackOverflow answers/questions yesterday, which was pretty neat. I guess he was just reading through them and upvoted the ones he liked.
Today all the votes were deleted and I might have even lost some additional rep. Did he trigger some kind of safety mechanism and then cause a recalc on my account?
I'm just curious if this is actually against the rules, or if it looked like abuse. I could see that and it's no big deal. Although, for the record, christmas is ruined.
