Seeing as you have posted this on every gambling forum around, I'll post what I said earlier ?
I had a meeting with GAMSTOP on Wednesday and they confirmed that 90% of UK casinos/sportsbetting sites are now signed-up, that leaves 10% left who are in the final stages of implementing the service. The deadline has been extended to the end of Q1 for all sites to join or face licence restrictions.
If you have taken the decision to stop gambling and opted in for self-exclusion, no-one here is going to recommend a casino for you either on this post or privately. I also urge you not to join any unlicensed clip-joints overseas, you won't get your winnings and you may end up having your identity stolen in the process.
