Is there any posible way to filter who are going to make an ICO to be able to know if there are scam or not? And is there any bodies of law that would be able to punish them once they turn into scam. And what punishment should be given upon committing such the crime?
That is the risks in the digital world. There are always people who will fool others just to get money in illegal ways because they know that their real identity is hidden and people would not trace them. Sadly, you cannot go after these people because you dont even know where to find them. Punishment, maybe just let karma comes to them.
