Single-Site vs. National Self-Exclusion
Excluding from one casino only stops you playing at that operator. National schemes (like GAMSTOP in the UK) share your exclusion across every casino licensed in that jurisdiction, closing the loophole of simply signing up elsewhere.
What Happens During Exclusion
During an active exclusion period, licensed operators are required to block new sign-ups and marketing to you, and reputable casinos won’t let you reverse a self-exclusion early even if you ask.
