I don't think KYC for airdrops offered is fair for those who joined. Some ICO with airdropping is not also fine to get KYC for tokens worth almost nothing or a burger meal is not really fine. I observed it in some ICOs with airdrops that even with giveaways like that so small needs KYC? Don't fall for it guys, not worth it.
Having KYC for peanut airdrops is total rubbish. I won't even waste my time on it allowing those scammers the chance to perpetrate whatever. Why demanding KYC for a less than 1 USD reward.
