Do you believe that every bounty that uses KYC before release of funds, bounties, or tokens is a 100% scam? Because I see more and more companies are posting this as a requirement on their campaigns.
No, there shouldn't be any direct correlation between implementing KYC procedures and scamming. They may simply be required by the regulatory bodies of their home country.
That being said, you're definitely in greater danger if you disclose your identity, because you have no idea what they'll do with it. Make sure you do proper research before you start giving out your info.
