Most of the times, it's the project team and same here in the case of Combo too. Irfan_pak10 has nothing to do with the bounty distribution. He just has shared the promise he got from the team. That's how it works in most cases.

I request OP to check out whether the bounty rewards is in escrow or not + whether the gas fee for the distribution has been shared by team or not, before participating. I had cases like this. Team shared me the rewards but haven't sent me the gas fee which later caused a huge chaos at the end. I was waiting for team to send the gas fee, participants were asking questions everyday lol.
