it's not usually that straight forward, it's actually quite hard to identify a real ICO from a fake or scammed one because most of the promoters are putting a lot of effort in making it look legit, and to the untrained eye, investor and trader that won't be visible. They are basically offering a whitepaper, a business model, a legit website but are not serious for the long-term, it's hard to identify these kind of things which is why you have to come in direct contact with the founders and core team. Try to join their communication channel (telegram for example or slack) and start making tough questions, push them to the limits to see whether they indeed have figured everything out and do our own due dilligence before you invest in any of them.
