The self exclude features, is mostly available in many modern casinos like I've seen. So I just don't think its really necessary for the time lock. You just have to use this feature if you can't control yourself or your gambling activities. Most times I just advice one to try his best and control himself. Having self control is what determines your wins as gambler in the long term. Most Gamblers aren't able to control their self and thus end up becoming addicted. Just understand that when you find your self gambling too much, try as much as you can to take a break. This will prevent some losses that are uncalled for.
