I am not fan of airdrops in general, but KYC for airdrops is very unreal for me.
Regarding the KYC, I am completely against this. For me, it is dangerous to sent to someone that you do not know, never heard of him and he wants your id. I really hope to see civic project in action for the KYC verification. The whole idea of civic is exactly for this and I think that the ICOs should start exploring the opportunity, once civic starts operating in the whole world, not only in USA.
