There are a lot of projects that are now asking for KYC, i myself don't like it as it is against the basic idea of cryptocurrency and that is anonymity but with more and more projects asking for it, i guess we move to it. But i still prefer projects with no KYC.
Yes, I have never joined to a bounty that requires KYC. It's really not safety to send our personal information. There are a lot of bounty that not require KYC so I think we have no reason to join the bounties that require KYC
