Hello, I believe I understand what you mean. Frankly, I'm pretty sure you've never seen the casino review, which serves as a warning. The overview is clear, but due to UKGC restrictions, we are unable to show players from your country casinos without an actual UKGC license. I'm not saying it's related, but the majority of players in similar situations from the UK play at casinos with extremely low safety ratings. I'm very sorry to see this.

Are there any technical obstacles you can raise on your end to prevent further playing? This is what sent the other player in a more or less similar position:
If your goal is to make sure that you cannot get back into gambling, I would consider making yourself as difficult to reach and as difficult to log back in as possible.
For example, one option would be to completely close the email account that is being targeted and create a new email address, which you do not use for any gambling activity.
If you need to keep your current email account, you could instead make it deliberately difficult for yourself to access it. For example, you could change the password, remove all saved login details and remove the recovery methods that would allow you to reset the password yourself. You could ask someone you trust to help you set this up so that you do not keep an easy way to get back into the account.
You could do something similar with your casino accounts. Remove all saved casino passwords and automatic logins from your browser or password manager. You could also set up two-factor authentication and ensure that you do not have access to the recovery codes or other recovery methods. If you use an authenticator app, for example, set it up and remove backup/recovery access so you cannot restore it yourself later.
You can also use website-blocking tools on your computer and phone to make accessing gambling websites more difficult.
I know that none of this excuses the casino's behavior. They should respect your requests and your gambling concerns, and I understand why you want them to close the account.
