There is a positive side of KYC, an example of ICO taking this proactive approach is SwissBorg, where "most teams come from the banking industry" and protecting investors and clients is very important. Their KYC process is simple - investors are required to subscribe and provide personal information such as name, address and date of birth. He will then be required to upload an official identity card and proof of residence (such as an official government letter). investor's personal information and proof of identity are then calculated and compared to the legal database.
Great point. the KYC should be simple and minimal in term of information provided. It is also the symbol of commitment from investors that they are serious enough to provide personal information for ICO project. As long as those information are not used for illegal matter then KYC is ok, in my opinion.
