If there's any government officials reading this, it is important you all understand that the ban doesn't in anyway stopped your citizens from still accessing these gambling platforms online with their phones either through VPN.
Yes, agreed that there are some dissidents who may try assessing those prohibited gambling sites through the use of VPN but it won't be like when there's no restriction at all. There's reason why there's leadership in states and countries, and in everything we do. It's for the purpose of charting a way forward for others. If the leadership of a country feels gambling may derail its people and decides to ban it, it doesn't mean it's not aware that citizens will also feel impact of such restriction. It's just that it's looking at the large picture of what its action will result to.
Also, when gambling is banned in a country; it's obvious government of that country will equally lose revenue in form of taxes from that. Government knows all that.
