No, I don't consider self-exclusion a necessary feature in my case. I can control myself and avoid gambling when I can't spend money on it. I don't feel temptated to gamble and I know when to stop. And when I make profit betting, I try to quit with profit on my pockets before it's too late. However, I consider this feature to be important for gamblers who are having a hard time managing their gambling activity, since they are commited with the effort of stopping.

Because if there isn't commitment, a gambler can just create a new account on the same platform with another informations (maybe from another person) to avoid a self-excluded account, or even move himself to another online casino where can create a fresh account. With that mindset, the feature is worthless... So it really depends on the personal motivation the addicted gambler has to stop playing for his own good.
