It is very risky to participate in a bounty program where we are required to perform KYC to claim the tokens (but with some exceptions from highly reputable projects like Binance, etc.). Your personal info can be sold in the dark web and will be used for unauthorized registrations in various random websites, etc.
I would rather choose to sacrifice my potential rewards in exchange of data privacy. Our personal information is much more valuable than the amount of money that we have in our bank accounts, crypto wallets, etc.
