Plex coin, diamond ico, bitconnect, ReCoin and many more. It's good to see that those scam busters are aware of that and they wanna take the scam ico to the court and i hope that will be happening in the future.
But the problem is how they can deal with the regulation that is always different in many countries.
Let's say when you are located in US and the scammers are coming from abroad and how can you deal with it? i think that the possibility to make a report to the security exchange commission like SEC and that institution will try to create a call for another country to take any action to that scam ico.
Cases like that are really complex, since it requires the cooperation of many countries but most likely the country in which the ico was registered will be the place where the trial will have to take place, but if the ico was not registered anywhere and you do not have the names of the scammers it is going to be a real struggle to get those people to justice and most likely those that invested in those coins are never going to see their money again.
