I don't promote Airdrops that ask for KYC unless its real estate project, I joined Elysia Airdrop sometime around 2019 and I earned 45$ worth of EL token which is already trading on bithumb with very good volume. It's a Airdrop that ask for KYC to get paid.
Some airdrops are owned by scammers and they are doing this so they can collect data by asking for KYC, selling data is a very lucrative business in the dark web I read it in one article, people should check the reputation of the airdrops before participating
The airdrop asking KYC of everyone involved is bullshit. That's just the act of selling your information to others. So never do it foolishly, you will surely get in trouble in the future
