All the same, I do not quite understand, if a person has a gambling addiction and he is struggling with it, trying to recover, then all the same it is necessary to foresee in advance all the options for influencing the psyche.  Including reminders about casinos and gambling.  Of course, first of all, knowing about possible promotions and sending by e-mail, you should block such letters in a timely manner.  So I think it was just in the process of getting rid of the gambling addiction that the OP made a mistake himself.  Maybe the OP just didn't think about it, accidentally forgot to do it.  But I don't think casinos should be blamed for sending such letters.  Although we do not know the details, they too may have ignored the OP's request to exclude his mail from the advertising mailing list.  But in any case, for reliability, it was necessary to block all incoming letters from the casino.
