Occasionally I want to take a close look at another user's reputation to see if there's anything that smells fishy about them (read: vote fraud).
Is there any reason why the
http://stackoverflow.com/users/#/<name>?tab=reputation wouldn't give a complete history of all of a user's reputation gains and losses? Are there reputation-change events that aren't publicly visible?
I ask because I've run across a user that this is apparently not true of: their displayed reputation doesn't match my manual sum of their reputation record (and it's not a long, complex record).1 The difference is only some ~30 points, but that's about a quarter of their rep. They were last seen 8+ hours ago, and haven't had any rep changes of that magnitude in the past week, so I don't think it's any sort of caching problem.
1. I'd prefer not to identify them and thereby cast potentially unfounded aspersions on their character.
As always, hypotheticals make for lousy discussion and I know the user's character isn't stellar since they've already been banned for vote-fraud once. This user got the bulk of their reputation on one day when most of what they'd posted got upvoted. This is somewhat suspicious, but not necessarily something I'd want to flag someone over.
Despite everyone's takeaway from this question, I'm not really all that concerned about whether they need flagging. I just want to know why they're shown as having 133 rep when their visible rep events total 102 (by day: 8-2+80+10+5-4+18+10-23).
