Website of a project holds alot of information, read through those and you can easily identity the fakes. First they will have fake information on their team. There is nothing bad if you intend been an anonymous project but do not lie with fake details as that is a very red flag. Be anonymous and stay that way then wait for believers to invest. Next is the Whitepaper, if you intend investing in a project do well to read about their ideology and what they intend achieving.

You should also review their roadmap and consider how achievable they are  many scams input spicy and juicy things to attract speculators meanwhile there is no plan in place to achieve all they have stated on their road map. Project that are genuine are usually more on developed then marketing bit the scams focus on marketing without any product.
