In the accepted answer to the question How does the bounty system work? it says,

If the author offered the bounty, and accepted an answer that was posted during the bounty period, that answer is awarded the full bounty.

Otherwise, all or half of the bounty is awarded to the highest-scored answer out of those which...

  • were posted after the bounty was started, and
  • have a score of at least +2, and
  • were not written by the bounty starter.

Here the score of at least +2 votes means the number of votes it had at the moment bounty period is ended or at the moment calculation for automatic award is done? Lets say an answer had a score of 2 when the bounty period is ended and later it gets a downvote and score become 1. but its still the highest scoring answer. Will it get the bounty by automatic bounty award mechanism?

  • At the end of the 24h grace period after the bounty ends. Feb 9 '18 at 4:44
  • @Ano can't you see I have linked the question that you have mentioned as possible duplicate and quoted one of its answers as well in my question

  • Ano has now updated the FAQ, so it's answered there. It's better to have all (frequently asked) questions and answers about bounties in one place; it's not a shame having your question marked as a duplicate.

  • @developer That post has since been edited. Here on Meta, it's common to close questions as duplicates of FAQs, even if the information was later edited. Feb 9 '18 at 7:36
  • I didn't know about that. And that sounds a bit odd. Better to start a discussion on that as well ;)

  • Duplicate? Unfair! The related text in FAQ was added after this one is asked. Voting to reopen. Feb 9 '18 at 17:29
  • @iDebug I notice the same. But Glorifindel and Ano say in revious comments that it's usual in meta

  • @iDebug Once relevant info is added to the FAQ, it's an accepted practice to close it as a duplicate. It's not a negative mark against the question. Besides, the answer was there the whole time; I just made it more clear. Feb 11 '18 at 1:00

I think the term I use for this is strategic downvoting.

As per the post on the grace period that describes it unambiguously,

edit: due to a lot of whining valued community feedback on this issue, I decided it can't hurt to extend the auto-award period 24 hours past the true end of the bounty. So, the question will stop being a bounty question at the original scheduled time but the auto-accept calculations will always occur 24 hours after that.

It is at the end of the grace period. You don't have the 'advertising' benefits, but otherwise it counts as an active bounty. The automatic award only gets calculated at the end of it.

So, an answer that got +2 upvotes during the main bounty period will be ineligible for an auto-bounty award should it get downvoted to a +1 during the grace period.

  • Thank you for the answer. It clears my problem. But why letting this strategic down-voting happen? wouldn't Calculating the autoaward before solve this? have it claculated beforehand and award it later after the grace period?

  • Its a bit of an edge case, I suppose but in this scenario, it simply means that the bounty period is 8 days. Its simpler if, for example, the bounty is awarded between that period. Anyway, most folks wouldn't do that unless the answer was not very good, or they felt the answer didn't quite fit the bounty reasons.
