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 don't think so... That's only an airdrop why they will force someone to have KYC to get a free tokens? for me that is not worth it guys, you will your information, about yourself and then the airdrop tokens have a small value... I will not join on that campaign.
