Personally, I am not against KYC because it is used for legal and verification purposes for the project. It sometimes help the project to eliminate double and bot entries. However, investors, bounty hunters must be cautious of the kind of projects they fill KYC for because there are some projects who gather the data from KYC participants and sell them for huge sums of money. Airdrop normally give out some few pennies and I wouldn't risk giving my personal details for airdrop KYC.
it's funny if airdrop program require KYC verification.moreover airdrop program value usually below $20.and its not worthed at alll if we give our personal data to unknown people.even in bounty campaign that have huge allocation could be penny when it traded.
Even though we are getting low valued coins but people still submitting the KYC for 20$ worth but once after listing in the exchange we don't see any value to the coins, the value of the coin will drop below to 1$, so it is completely waste submitting the documents to the companies.
