i agree that OP shouldn't blame the casino, OP is complaining that the casino should block his IP, but we all know that when a person is addicted that person might even be able to use VPN and create another account and continue playing, so even if the casino blocks the OP's IP this will not be the solution to end the addiction that the OP has, and at this point the OP seems to refuse to notice and is angry with the casino. curing addiction is not something easy, it takes years, it takes willpower to cure addiction, if the person doesn't look for a doctor, doesn't go to the hospital and doesn't stop moving anything that has access to the internet, that person won't go get rid of gambling addiction
I believe the casino must not have realized that OP is a gambling addict, casinos do not have super powers and are not responsible for someone becoming addicted to gambling, they have no way of guessing or knowing that someone has become addicted to gambling. gambling addict unless that person informs the casino that he is a gambling addict and asks the casino to block his account, but if that person creates an account again and with the same name and email then the casino may suspect that this person is addicted to gambling and may block the person's account
