It is actually not the casinos problem but the person itself however the casinos can prevent it if they are going to be a little strict in regards with their players but due to competitions like here in the forum gambling sites that is not strict is more favorable than those who implement rules in regards with KYC. It is just a game and a leisure but if we don't managed to control our self and did not become a responsible gambler I don't think this will be the last time that this kind of incident will happen.
Nope, this won't end just because they will imply strict policies to avoid players getting addicted to it. Gambling addiction is a choice, and the person who is addicted won't be healed unless he will help himself with some medications, and the help of professional therapist. Maybe the said individual is rebelling to his parents due to lack of attention, love, and care, in my opinion.
Rehabilitation is a long run, that's why families are the one's who should be patient on helping their love ones in the process until they are healed, not nagging at them because they are addicted to gambling.
