And not just that, they'd go for here to another one if they're so addicted even if they have applied the self exclusion. Yet, they can't stop the urge to gamble again because that's what their minds are telling them and that's to keep on gambling regardless of where they ending up. All they wanna do is to gamble and maybe find some of those faults to the next casino even they know that it's their own fault for continuing.
Being addiction in anything is really hard to resolve, it takes time, cost and very strong mentality as well as discipline to change their mindset firstly, then habit gradually with time. Most people fail to do that and by continuing their addiction, they will move around and do what they are familiar with like gambling or trading. Platforms are not responsible to do anything on behalf of users for rehabilitation on any activity, it's up to users for doing this individually.
Self exclusion is only one feature to support users but if they can not change themselves, they will repeat mistakes by looking for chances of playing at other casinos.
