KYC does aim to reduce cheating like multiple accounts on a bounty or airdrop, but many bounty hunters don't agree
with KYC in a bounty, for me it's not a problem filling KYC if the project is potentially good in the future
the problem is that many teams are very unaware of the data obtained as a result of the ICO and KYC. Personal data goes to very different places where it is collected and illegally processed.
