I have recently seen where bounty hunters were asked to present identifying documents. Am really against kyc because one of the reasons I joined crypto was the anonymity which it provides. But sadly that's gently creeping away.
Now this KYC has come into airdrops. Imagine am to submit my ID to some I don't know which planet he or she or they are from for some pennies worth tokens.
It's terrible and this is a bad precedence these people are setting.
If as a community we do not say no to this, then it would become the norm.
KYC is needed because some countries have banned their citizens to participate in ICO , surely airdrops often are part of ICOs and I believe airdrops could easily be mentioned in such laws as well. Project management is responsible of complying with these laws and the only proper way of doing it is KYC. Because of this KYC will not be going anywhere, the opposite is going to happen - we will see it more often.
My advice do not participate in shady airdrops.
