KYC for airdrops???, I think what you mean is KYC in bounties. Airdrops doesn't requires any KYC of some sort because its a free and trial tokens. Don't join airdrops that requires KYC because its pathethic and it might just steal your information or scammed you. Nowadays airdrops in bounties are very common because developers are trying to identify cheaters and they want to have an idea who their customer is.
