Bounty hunters don't hate kyc. It's risky putting out your personal information out there for a project one is not sure of, there are many scam ICo's out there and identity theft is high now. Another reason is the that devs are not being sincere, they ask for kyc when the bounty is over not at the beginning of the bounty thereby making people work and some will not get their tokens because not everyone will pass KYC and the devs know that many people will fail kyc so they do it deliberately. The kyc issue is becoming too much, people did bounties in previous years and no project asked for kyc but these days almost every project is asking to do kyc of which some are sCam project.
