It's becoming more harder for new projects team to keep their promises to bounty hunters, some even said bounty hunters are getting free tokens for free, meaning bounty hunters aren't recognized for their work, I suggest all bounty managers to start using ESCROW.
I believe with escrow payment will be guaranteed, team won't be able to go back on their words, bitwings for example, after a complete year of waiting for payment they decide to do another audit on spreadsheet and they falsely accused bounty hunters without any proof.
Bounty Detective is the only bounty manager using escrow, if many bounty managers start using escrow it will be better.
It is totally absurd saying that bounty hunters get their tokens for free. They are not free! They are rightfully earned by them for their hard work done in order to promote the project. Necessary publicity and marketing are achieved by the projects due to the work done by the bounty hunters. I agree with your point that every bounty manager should start using escrow.
But in that case, all the managers using escrow should be trustworthy. The whole funding of the bounty or signature campaign will be in the hands of one single entity so make sure to choose the right person for the job. Many scams happen these days and to be honest no one can really be trusted.
