I personally believe that any airdrop asking for kyc is a scam, asking people to submit personal information to obtain an insignificant number of token is laughable. One could argue that its necessary for identification process and to curb the utilisation of multiple accounts, but I still believe that kyc is only necessary for investors who purchased the tokens. Going by the meaning of KYC - Know Your Customer / Client. Airdrop participants cannot be categorised as clients to the company because no transaction was made.
