Only 3 of the listed ETH address are not registered (the last one for example). Those who are not registered will not have an airdrop because there's not EOS tokens there. However, they did win the 5K CNT prize (thats why everyone is above 5K).

Tell "your friend" (if he is one of the tree) that we will be dropping the tokens on the EOS address generating from the ETH private key.

Thanks for asking.
