All airdrops listed on nextairdrop.com are checked to not be scams or fakes. Always pay attention when you have to send information to airdrop projects. Airdrop projects should NEVER ask for passwords, private keys, pin codes or other secrets. Some airdrops do ask for your PUBLIC ETH address because they are Ethereum based tokens which they have to send to a existing ethereum wallet. Only giving the ETH address to someone does not give them access to retrieve tokens from it, only depositing to it.
