Escrow only ensures that the managers get tokens,,, but as you see even the high gas fees are a problem. If teams are not even willing to pay bulk transactions for bounty it is a huge sign of mismanagement of Ether. Why not they use Layer 2 solutions like many exchanges are already doing?
At least it would be fair to all parties to the agreement, which is conditionally concluded for the Bounty company. Escrow is primarily a guarantee of trust in the project and an indicator of the real intentions of the team, as well as real confidence in receiving a reward for each Bounty Hunter. In addition, in the proposed variant of the course of the problem, each bounty manager will be under strong supervision and authority will play an important role.
