Yes. I am putting it together to send it to them, but I hope that this post will also serve for other sites, since I noticed that in almost all of them, the exclusion is not by IP, it is by individual account,
Even if a casino block your original IP, you still can create a new account by changing your IP through VPN or other things when you want to come back. Once you requested a self-exclusion, you should try your own best to stay away. The key is on yourself, if you feel that you have a gambling problem, so you should find the best way to overcome it.
