Before paying attention to the 10 guidelines that the OP calls, I first look at the Innovation of the project, use cases, products, and how important the project is in the future. Scam projects can be identified with fake teams, plagiarism whitepapers, or content that copied previous projects. Scammers usually promote their projects by promising multiple returns on investment or does not make sense. and only gullible people become victims.
i'm sure most of the projects these days is hard to be identifiy just by the team members, contents or whitepapers. a non-plagiarism or good whitepaper doesn't mean it will guarantee you with the legit projects. the projects that have a real team members also can become an abandoned or scam projects too in the end. that's why OP shared some other ways to identify the scam projects.
