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.
If kyc is included in the rules then that's fair enough since you're already aware at the start so you have the time to decide if you want to join or not , otherwise this is one way of showing the legitimacy of the project , even you are not an investor but you're part of the team.
