I did not know the exact information about KYC before. However, I found out a lot after the pig in this thread. I will think 10 times before doing KYC in future. Thanks Friend for sharing such information with us.
It's pretty dangerous to submit KYC. Don't think about it. Avoid platforms that require kyc. I know there are times that it could be an exemption, like on casinos that will request KYC berore you'll be able to withdraw the jackpots you've hit. But if just for airdrops, bounties, etc., do not pass any.
