What is always a big problem that is difficult for most gamblers to do is "letting go", I understand that losing money is an undesirable situation, but remember that this is gambling which is an activity that leads to one of two possibilities at the end of the session between winning and losing, and I think everyone already knows that gambling is a risky activity, meaning that losing is a part that can never be separated from gambling.
This means that I believe that by having the right understanding, letting go and letting go of something that has been lost should not be something that is too difficult to do, understand that self-acceptance regarding risk is the main part that must be owned and always prepared by gamblers.
That is a problem for many gamblers, for my part I prefer to think about the money I gamble as already lost, this way when it actually happens there is nothing for me to get mad about it, and if I happen to win then I know that if I gamble that money again then I need to consider that money as lost too, so by just changing this view I have towards the money I use to gamble, I do not suffer from any issue controlling myself and avoiding obvious scams like the one described on the OP.
