The gambler should do sufficient research about a gambling site before using it.
It's not completely anonymous or decentralized because most casinos now that are operating are registered, which means the regulators know the owners of the site and they can go after them if they break the terms in the license issued to them. Therefore, it's still helpful if the government will intervene to protect gamblers from scam gambling sites.
we have seen so many casino in the past and until not that has this attitude.
i will not mention one but it is obvious if we will go through scam accusation board and even in gambling section in which the victims continues crying in their respective ANN thread .
@Fredomago only some of the newbies won't understand that some casinos have gone from good to bad but the major reason why some casino hide their identity was not the intention of scamming their users though it is not possible there won't be some casino who will abuse the decentralization and anonymity benefit.
