The casino doesn't have that right or any obligation to freeze your account for irresponsibly gambling. What is even term as irresponsible? Because you lost? It's not fair, I will not use such kind of casino because what if the losses were from your own mistakes? I have I many questions but I think this is why we need to always read the terms and conditions of casino when making a new account, for them to do such, they must have indicated it in their terms and conditions but because we don't care to read them, we accept it without even knowing the things we accept.
The gambling platforms I used all have suspend accounts but it has to be done by you and the moment you activated the "suspend account", they will ask you to confirm from your email and once that is done, they will not activate your account again until that time has elapsed. Should you change your mind later, they will not open the account because they think you are addicted, the first condition will remain which is suspended until that period has elapsed which is good for gambling addicts.
