In fact, I have never seen or heard the news for punishment for the person in charge of the scam project. Who is responsible? The question should be when the fraud project will occur, it should not be given space. In order not to harm many people in terms of time, money and energy.
In the past there were a lot of projects who scammed people and was never punished the reason was that in that time it was hard to find that which project is scam and which one is legit but now people can know that which one is legit so no one can scam and people invest only in those which team members are KYC verified.
