Team is the heart of a project. The success of a project depends on the team. If the team is anonymous, then investors and participants will lost hope with that project. In fact, the projects has anonymous team is more likely to be a scam project. Also many scam project use fake profile, picture of team members. So I think it is better to stay away from anonymous team.
absolutely right, when some people make a projects, it means that the project must create products. if we see the projects with the anonymous team member, we don't know the team capabilities, histories and experiences. are they capable to create the products or not ? if they're not, i'm sure the projects will be abandoned, then turn become a scam project.
