For Airdrop, big NO. I will never follow the KYC procedure to claim airdrop rewards. Besides the number of airdrop rewards is rather small, airdrop seems not to deserve to require the participants for KYC.
For bounty, I will take a look at the project first. If it is a trusted project, I will consider following the KYC procedure. While if it is a bad crypto project, I'll ignore and refuse the KYC procedure. It is always very risky sending our private data to others. Moreover, there is no guarantee for it.
