The airdrop asking KYC of everyone involved is bullshit. That's just the act of selling your information to others. So never do it foolishly, you will surely get in trouble in the future
Yes, because basically the Airdrop program is free without asking anything to the participants, whether it's KYC or some kind of payment for a token claim from Aidrop, so don't give anything to Airdrop especially Airdrop which currently has many unclear origins.
the problem now is that more and more groups are promoting unclear airdrops. only a few pay cheaply, sometimes they are asked to do work and provide their KYC documents.
