The aim of self-excluding your gambling account is to take a pause from gambling, whether from visiting a local betting shop or a casino. If you self-exclude from one casino and then jump to another to play, it's the same thing, it didn't help.
Before self-exclusion, you should have mind exclusion from gambling first. Withdraw your mind from the thought of playing for the period you want to reevaluate your gambling habits, budget, and everything. Just take a pause.
If you self-exclude and then move to another gambling shop to play, what's the difference? You literally didn't do anything; you just moved from one place to another. You wanted to self-exclude just to feel like you made an effort, but you went back again.
I know self-exclusion is a step towards curbing excessive gambling habits, but you have to be intentional about it. It's not just about making an effort or having the thought; you actually have to work on taking action.
I've heard people say they've self-excluded, but they still gamble online through another method or different platform. It really doesn't change much if you don't withdraw your mind from gambling and going to casino for that time and legitimately stop trying to open a new account, or try a different casino.
