I think no ico scammer has been brought to justice uptil now but many cointries are busy in setting rules and regulations where only legit ones will be allowed to raise funds and the scammers will be caught and punished.
How can they be caught and even more so, be punished when there is not a single body directly overseeing the cryptocurrency? This is one of the dangers of decentralization and free market.
It seems to me that for fraudulent ico companies are punished only by members of Bounty company and bounty managers, For disseminating information, because real villains are not caught. And nobody cares that they can also be victims of scammers. The color of the account is not fair. In such cases.
