KYCs are not the problem here. The problem I see is where you are entrusting your information to. Because their are certain ICOs that will only fish out your information as it has more value for them rather than the token they are creating. KYCs are a requirement of some countries' government as it is their way of regulating or being in touch with their citizens. What I would normally do before trusting my personal information to other entities such as ICOs or even exchanges I will research on them if they have a good background.
There are people who are not willing to put their personal information even on social medias that's why if the developer and manager would want a KYC then they should be transparent also of revealing their real identities since it is almost likely that you two are meeting each other in a single place. By doing this i think it would help the investors to get some ease of being scammed by someone that who doesn't have a real identity.
