How does the bounty system work?
When someone asks a question and puts a bounty on it, but doesn't select an answer, the bounty goes to the highest voted answer with at least two up-votes. What happens when two answers are tied?
From @ccomet's answer-comment:
From the Bounty FAQ:
The answer with the most votes is automatically accepted after 7 days. The bounty is subtracted from your reputation. The answerer is awarded half the bounty amount. If more than one answer is tied with most votes, the first answer receives the award.
Emphasis ccomet's/mine. Posted so there can be an accepted answer on this question. Marked CW only because I don't deserve rep for this.
