Depends on where they are and how good have they covered their tracks on the internet. I remember for instance case with benebit where team members even gave FALSE KYC registration when needed. So sometimes it if they do it right it is really hard to undercover the people behind the scam. In many countries, if not all, people who run such scams should be punished. So such cases we can report to the police, specially if you were the investor and they tricked you. The bad side of this is that there are really projects that are trying to some good but because of bad reputation these scam give it makes it harder for legit projects to come to surfice.
