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 are right, it is related to one's personal data and it is strongly recommended to read the rules before you continue the next step in a campaign and it all depends on how the inisation from a manager to manage a project whether KYC is deemed necessary or not.
