LoL how come it is stake's fault? Responsible gambling is bullshit in the first place. If a person don't have any control over him/herself, why would that be stake's problem? He/She needs professional help and that's not among stake's responsibilities. What stake responsible for is providing us an honest/fast casino. You just can't ask more from them.
There is a mistake from the Stake side as well because they still send promotional email to player who have requested Self-Exclusion due to a glitch in their system/server. However, player also made a big mistake by creating new account because he is triggered by the promo. He is aware that he has gambling problem, he should have ignored those promotional email but in fact he decided to create a new account-play-the lose his money-asking refund. For me asking for refund does not make senses in this case.
