There might be a possibility that it really is a scam. But usually they're getting smarter as well as some of them build fake profiles just to fool investors into thinking that they indeed has a good public track record. It will always be better if they're active in social media and observe the community he's currently in to. It'll pretty much tell you if they're real or not. NeuronChain is one of the ICOs I've been following though. They fit my criteria when it comes to the team and the working product that's already on the mainnet. You can check their Facebook if you'd like to check it yourself: https://www.facebook.com/NeuronChain/
