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 agree with the above statement. Technical details we can look simultaneously but for me, the important is - do they really have use case to implement or just using some sort of front to attract buyers? Because you will know if their concept is viable and ready to implement, when you check their whitepaper and their plans how to execute it. Actually, it is better to invest if they already have the working platform with users on board not just only in beta stage of their product.
