The forum, ask gambler or any other website can not harm them much. I think the victims need to take them in the court and the legal authority help to shut the site down. Only then we will not see anymore victim from them.
All the victims should form a group and launch a class suit, they have huge money to advertise and pay people, and the people they've scammed have proof and evidence, they just need to band themselves if they have whales that can help them put his people to trial then we'll have a chance to shut down 1XBIT, we can only warn people but to stop them from scamming more people a court order is the one to do this.
