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.
Its true mate never fall for this KYC required airdrops because not just because of scamming,but a chance of being a victim of Hacking or may used your data for other connections from illegal or criminality.and I dont know why needed to bring complete details for just an airdrops?This not even fits the essence of crypto community of decentralization and anonymity.so better get away of these guys because for security measures
There is no legal reasons to do kyc without investors, so you would have to wonder why would they want your personal information.
