I feel worried about the identity of being abused by irresponsible parties. Not appropriate for coin promoters or tokens to request KYC for a small number of tokens. I think a few drops of air can be set to get a copy of ID only. For the rewards program I consider it reasonable, but for airdrop programs there should be too much KYC.
I think that KYC for airdrop is the most absurd solution they could come up with. Payments are rare and scanty, and here instead of solving problems with scammers, introduce KYC.
