Hey Pringles,
Haven't heard about this incident too much, all I can say is that a bank or payment method will never go in by their own cause to stop a person from making deposits unless you already sat a deposit/transaction limit on your account. So yeah I agree with you. of course you can get tilted on gambling and therefore it's a good thing to have a limit or as you say be strong and responsible.
But everyone's mind and tolerance are different. Some people don't have the strength to quit, set their limits and think in the same way you are writing. Therefore there is very important to talk about this subject and to show that there is actually help and tips for those who is addicted.
Much love
