This KYC is basically about extracting your personal data from you - in case of an airdrop this KYC (Know Your Client) looks like bullshit. They claim they have to verify your identity (you are expected to provide copy of an id) for no valid reason. In exchange you are getting tokens with very dubious value and you don't have any control over the data you provide. In my opinion any "airdrop" with such requirement should be avoided.
