Habits of any kind come with their own rulebook, and reading it before you commit is rarely wasted effort — the same holds for UK players who have self-excluded through Gamstop and then start weighing up offshore operators. casino not on GamStop sits outside that self-exclusion scheme, usually under a licence from another jurisdiction, so the protections you may be used to do not automatically carry over; reputable operators still offer deposit limits and site-level exclusion, and checking those tools before depositing beats discovering them afterwards.
