14 days from issue closure to being able to make a claim request.
First claim requests are voted on first, by each bounty contributor.
Undecided claim requests are decided by the majority of the votes. If no one has voted at all, the bounty is still payed out.
What to do with scam requests? How much do they weigh?
Each voter only decides what to do with their part of the share. If a voter does not vote to pay out the bounty, the voter is instead taken to the next claim request to vote there, until payout is decided.
