Only a few ICOs have I seen that are scammers and showing their face, and at the end of it all they still got caught. And some of them were not really caught , but due to some kind of financial issues and they happened to fall. Most scam projects prefers to hide their identity, and if they can’t be anonymous with the project they are launching, they will try to do what’s called impersonation, pretending to be who they are not.
I have seen so many scam projects that people later trace their team members only to find out that they are not the real people, but just scammers pretending to be people who have no single idea about the project.
