How many of them actually pay the money they promise. I doubt it. Most of them will ask you to go through KYC and still there is no guarantee that you will earn those tokens.
For a small amount of $10 I not happy to go through KYC my identity is far more valuable than the amount they are giving me.
Doing KYC for merely 10$ is not enough to save you from possible usage of your information. Some of the list are traded on exchange as long as this will not harm your private info then its good to go. I joined some on the list, but dont ever joined airdrop that asked you hard KYC info. An eth address wound not hurt you giving up but other than that like ID its a big NO NO!
OP can you segregate the list of KYC and none KYC airdrop?
