According to Meta StackOverflow question 21529, I know that it is not possible to remove a bounty once it's been started.
I answered StackOverflow question 3251056, on Thursday, September 9th, when the question stated it had a bounty that would end in 12 hours. Now I'm not seeing anything about the bounty, and according to the revisions history on my answer, I answered the question yesterday, Friday, September 10th.
- What happened to the bounty?
- Why does the revision history show the wrong date for when I answered the question?
