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.
It's really not worth it but still, people like newbies are falling for it, imagine exchanging your personal info for just pennies worth of token, these devs are the one who is going to make a profit when they sold your info in the black market and you will regret it later.
