Not a secret, there are gamblers who unable to manage their gambling activities, win some and lose a lot. It's really unavoidable especially to those high rollers.
They might be hitting jackpots as they can afford to wager and they've got enough funds to continue chasing the big odds but in the back of that, there are also many loses to suffer before you find that luck to hit it. Some may able to manifest the wait and take out the winnings.
While others become more greed and try to win more but eventually ended up
busting everything including their entire bankroll.
Unfortunately gambling is a bit like that, a lot of people gamble and a lot of people lose, because they do not know how to stop. I would love to say there is a cure for that, but unfortunately only thing that can stop them is themselves.
Casinos nowadays even allow you to mail them and close your account and even ban your IP just to help you get rid of gambling addiction, most casinos wants to make money from gamblers who have fun there, they wouldn't want to have gamblers that lose their food money, because if you keep gambling 50-100 bucks a month for 50 years to have fun that is more profitable for a casino than you gambling 10k and lose it all and starve to death. At the end of the day I would say best case for us would be to make the information of being able to get banned at a request more popular, if we can make that more popular we can help few people.
