This is something someone put on another forum- they claim to be clued up about the legal side and put this…
Every UK licensed gambling operator is required by the regulator to engage with the GAMSTOP program. There are no exceptions to this rule anymore.
The only casinos that will accept UK players that are not part of the GAMSTOP program are casinos that are unlicensed and accepting UK players illegally!
It is not legal for any casino that does not hold a UKGC license to accept UK players. Any casino not on GAMSTOP does not hold a UKGC license. However, it is the business that is committing an illegal offense, not the player.
