Many bounty managers don't like listening to what bounty hunters have in mind but this won't stop me from saying the name of two bounty managers that listens, they believe in fairness and good contribution of their bounty hunters
1. Bubbalex
2. Bounty Detective
OP, I will say a capital YES for Alex in all you said concerning him. The dude is exceptional and believes in quality as against quantity most BMs dwell on. Alex doesn't just bring the bounties, he follows them through to the end making sure qualified hunters get the rewards. But I can't say same for Bounty Detective. BD doesn't follow to the end or escrow the reward. I suffered the misfortune of participating in the AMZ bounty which BD managed and I eventually lost my reward (which was distributed to our accounts on the AMZ site) and then made KYC an issue. Hunters couldn't withdraw at the end and those affected got their tokens wiped off. I will suggest that the BD should do all it can to follow any bounty to the end and into distribution. Otherwise, it's just a matter of time before it loses credibility among hunters.
