I'm wondering if there are any statistics on how many users actually use features like time alert and self-exception. I think that users who can control themselves don't need such features.
I think it is most important for users to develop self-control because even though casino platforms may have features like this to assist, they never really do the job completely if you have not convinced yourself that you require some self-control to actually help yourself.
Addicted players, on the other hand, are likely to ignore such features and look for any workaround just to keep playing the slots some more.
A gambler who self-excludes from one casino but has not developed enough self-control to stay disciplined to his decision can decide to go gamble at another casino while the self-exclusion at one casino is in effect.
