Most ICO's tend to hide their members behind the project. Is not it necessary to know about the team also who are building an ICO project, including other factors of it?
It is mandatory that you check if the persons behind the project say who they say they are and if their credentials are real, I would not have any problem with anonymous developers if they said that from the beginning, but if they try to use the identity of someone else then you know they are scammers.
