I feel like it's not fair for bounty hunters to submit KYC when joining bounty campaigns because we are not an investor. We will never be involved with any anti money laundering because we don't invest with money but with TIME and Effort instead. Personally I'm NOT very comfortable submitting my ID's for the simple reason that these are startup companies and we don't even know if they can be trusted.
You have to understand that they do it to minimize the acts of fraud that occur. Like doing a multi-account for participate in 1 bounty. That's obviously not fair, because each person only has one share. Such requirements are also sometimes at the request of the project itself to avoid fraud that harms the project. Bounty and airdrop are made as a promotional media, if they are misallocated to greedy people, then they do not benefit from the bounties they hold.
