I think that's not balanced our identity is attached to the KYC form by only joining the airdrop. Assuming the tokens found are very low in the market.
But on another side, i think a purpose of KYC in Airdrop aims to avoid the multi-member accounts that follow. So a cheating on the distribution of tokens can be minimized by the airdrop #DevelopmentTeam , and also the airdrop developer can find out which country the participants came from. And that as a community database of their project.
I usually avoid the airdrop asking for KYC, because of an imbalance between our personal data documents with token values. I doubt it.
