It caused by there was no report to the SEC, if there are some people might come from US and this scam project can be reported to the SEC. It's better to do that to get your money back and the team will have jailed by SEC.
From what country the team are raising money? if they are not raising from US, then they will not be subject for the Law of the USA.
Anyone can give an information, that would be helpful.. but I think we can't declared the project scam already.. am I wrong?
