I heard Philippines government are like shit, so banning gambling won't solve the issue to make people stop gambling.
I'm sure they will gamble on online casino, the government might aware if there are local online casino and their citizen make deposit through banks.
Most people gamble with a purpose to make money, Philippines is a third world country, that's why many people are addicted to gambling. Instead of banning gambling, government should find a way to make the citizen life better with minimum amount of salary.
