I was also surprised to see WhaleHeaven campaign on this list. OP sees in what way to include WhaleHeaven campaign in this list. Is it just because every Bounty managed by Bounty Detective is a good Bounty?
WhaleHeaven is not managed by Bountydetective. I don't think every project managed by the bounty detective will be included in the list, because some projects are not included. It seems like the OP is only focusing on paying campaigns, but it doesn't matter whether it can be traded or not later.
