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.
I am very surprised that people pay very little attention to the fact that they live in the system, and in this system, your data has long been known and, if necessary, they can always be found and all questions need KYC or not, absolutely useless.
