I don't think it's easy to prevent a project scam. The existence of an ICO project is to get funds or to attract investors to want to invest in the project and later the funds are used to develop the project, if the project can go according to plan and succeed then we will also get the results. So I think it all depends on the decisions we make based on the observations we make, don't rush in assessing a project, know more details about the project before making a decision.
