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.
