I would like the see casinos act in this manner because it will assist in stopping gambling addiction. Sadly casinos are profit-making organisations so they will always want bettors to keep betting. If a casino freezes my account because of suspected over-gambling, I won't be angry or consider opening another account. Waiting for three weeks will be my best option because it is clear that the casino cares about my well-being. I will be loyal to such casinos because they care about customers.
Indeed, it might not stop the gambler from gambling because the process of opening another account is easy. However, some gamblers might decide to wait until the suspension elapses if they are used or loyal to the casino. I have played in some casinos but I am attracted to few because of their quality service. There are some casinos I will never use because of the bad experiences I had, so I might consider waiting for three weeks.
