Last week, I tried to open a bounty for a Stack Overflow question of mine. Unfortunately, there was only one answer posted, and it's not been helpful (mostly posting results to some Google search which I had obviously already done myself).

Today, I received an e-mail notification that the top-rated answer "may" be auto-accepted once the bounty expires. This confuses me, and searching here on meta hasn't really made it any clearer.

What criteria are used for auto-accepting an answer? If something does not answer the question, it should never be accepted, imo. I gave the guy an upvote for effort, but since it doesn't help me at all, it seems unjustified to award him a 250 point bounty?

Did you check the https://stackoverflow.com/faq ? It covers bounty quite extensively.

  • Thanks, that clarifies the "may" bit. I don't understand the design choice of never allowing the OP to accept an answer anymore. Should someone provide a useful answer after the bounty period has expired, it should be possible to accept it? There has been some discussion about that here already though, it seems.

You may consider for a moment that you (and maybe others) might have caused the mechanism to fail. Giving an "A" for "effort" only obscures the grading system. Your supposed to up-vote an answer because (from the tool tip) "This answer is useful." That's what you are telling the system—answer is useful.

When the system auto-accepts a bounty, it is accepting the "most useful" answer. Reputation is a measurement of how much the system "trusts" you. That's why it takes a certain reputation to vote. When the system applies the rules of auto-accepting, it's only responding to the information you and other users gave it.

  • Generally speaking, upvoting is outside of the control of the OP. In my case I did contribute one upvote. In the end I answered my own question with a somewhat unsatisfactory answer, but at least I can update that answer eventually, rather than being stuck with a locked in accepted answer that doesn't solve the problem.
