I've checked and the casinos ain't what promotes those addictive problems or the irresponsible gambling habits.
It's best decision for every gamblers to react as they want. The casino companies are only there to provide the services while you take your position.
Aside casinos inefficiency to keep good reputations, I don't think there is further way they can go to help gamblerss eliminate the owned problems created by oneself.
If you think there should be a party to curb the visible issues as addiction on gambling, then it should be the regulatory compliance to implement gambling policies to help the situation. We also don't need anyone to direct or redirect us on our decisions, we just need to be aware of the potential threats and avoid them.
