Here I see a user with 602 reputation gain this month. But there's nothing much on their activity tab. Can someone tell me what's going on?

@ShiveringSoldier His/her previous answers/questions could get upvoted. He could get a bonus of +100.

@Knight Are you talking about the earned bounties? Anyway, AFAIK, everything should be reflected on their reputation tab. I don't know, may be a bug.

@ShiveringSoldier For what it's worth, that user doesn't appear in the Monthly reputation league.

@quid (or any other moderator) Would it be a terrible abuse of the bounty system if I offered to award a bounty on a random post from any user to can fix the orientation tag? :P

How much of an abuse?

How long would the suspension last?

@ArnaudD. Yep, it shows a monthly reputation of 4 here.

@ShiveringSoldier a question was deleted, this refunded bounties placed there. It's a bit surprising that it is displayed differently at the two places.

It being a deleted post it does not show up for other users in the reputation tab.

@XanderHenderson It's not that terrible, as far as I am concerned. I'd offer that the user can choose the post. Likely some other are more rigid than I.

"Abuse of power" is an impeachable offensive :P

Sorry if my above^ joke is in bad taste.
