So those people can not blame gambling is a scam but they can called the owner is a scammer because he runs his business without thinking about his members. So that is why we must makes sure that the casino is safe and we can trust it when we use it for playing gambling.
In other words, scam is caused by human behavior. In this case, the casino owner is the scammer and gambling is used as a means to carry out his cheating. Obviously, this is not the fault of the gamble but the fault of the casino owner and the fault of the gambler. Because the gambler was careless in choosing the casino and chose the wrong scam casino, if we choose the right reputable casino, we will not be scammed.
After all, gambling is just a game, a means and product...created by humans like everything else created by humans. It cannot scam anyone and all scams are people using it to scam others. So instead of blaming gambling, let's blame the scammers or ourselves for our bottomless greed.
