What is automatic awarding?
Approximately 24 hours after the end of the bounty period, if the bounty starter has not manually awarded the bounty, the bounty may be awarded automatically.
If the bounty starter accepted an answer during the bounty period, that answer is awarded the bounty. Answers accepted before the bounty period are not eligible to be awarded the bounty automatically.
What if the bounty was not started by OP but by somebody else and answer was accepted by the OP? Will the bounty be automatically awarded to the accepted answer still?
