I distrust airdrops that requiring KYC for it to be receive. Even though it is a legit site for other users. Also I have read some replies that the KYC verification is still pending and from that, it already shows some shady acts.
KYC on the blockchain wallet is needed to get instant exchange so users can buy their needs, regarding airdop must be KYC for a long time cause some users are worried about using multy accounts. They are legitimate and honest cause the site has been around for a long time so I personally believe in the blockchain.
