It was really a suspicious move but anxious hunters neglected it. Why ask for only a passport for KYC and not any other document.
My advise to bounty hunters:
1. Don't participate in any bounty without escrowed rewards.
2. Don't be in a rush to participate in every bounty that comes up.
3. Follow only trusted Bounty Managers.
4. DYOR on any project and don't rely on BMs. Most of them don't even research a project before going into contract with project team.
Anyone else got any advice for bounty hunters, especially the noobs among them?
All the advise you gave are really helpful I just hope they will heed to them, well here's my advice to them, never disclose or share your personal information with any project in order to receive rewards after you have participated in their bounty campaign, don't give out your private data in the name of kyc.

If it's about following a trusted bounty manager, just so you know the bounty was handled by bounty detectives,and we all know their reputation precedes them,it's not their first bounty campaign here either, cus they have managed so many bounties on this forum, they slipped out this time, thats why I no longer trust them "fully", they should at least paid those bounty hunters who did all their best to make sure the project was successful
