Say someone gets a Mortarboard due to serial up-voting. I know that badges can't be reversed. But, votes can. This case is somewhat interesting and I'm curious. Today (over Physics.SE), this user got a load of up-votes. In fact, we were discussing about the upvoter & the reversing scheme (see the whole transcript). Within a few minutes, the guy cleverly used this 200 rep. to offer a bounty over this question
What I'm wondering is: The engine has recorded the pattern of votes. It will definitely do the reversing. Now, this guy only has 25 rep. The minimum rep. score that a SE user can have is 1. So, the score can't go negative (neither zero).
So to be clear, what would happen tomorrow? Can the system be cheated this way?
To future viewers: The problem has been resolved and the bounty has been revoked. See his profile. I think the rule has been implemented that Bounty shouldn't be awarded if one experiences serial upvoting
