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.
Yes, it really is not worth it. I think that the airdrop brings very little bonus to the bounty hunters but they demand too high. Those who participate in the program must cheat to have more money than they deserve.
