You should not playing online gambling using your phones because you can get a problem from the authorities. If you want to playing gambling, maybe you can play when you are in your hotel and no one knows what you do. But that is not a suggestion because we don't know how strict they are with a tourist.
Yes, you should not gamble in public places, especially if you are close to the police station, it will get you in trouble.
But if you play in a place where there are no officers at all, people won't care.
Indonesia will not be as strict either, what you see in Berta about checking the phones of visitors or tourists is just a formality for a to-do list,
even though they will not do it every day LOL.
But still he must concerns not to playing gambling in a public place even if there is nobody there. That will still gives him a risk because he never know when someone coming and watch over him playing gambling. Maybe what you say is right about the Indonesia is not too strict as in the new but we never know the real thing that can happen.
It is better to prevents than gets the problem
At least, we knows what we can do and don't when we are in other country.
Indonesia don't have a local casinos so you will not find that in all cities. But if you can talk with local people, maybe they know something about underground casino.
And yes, if you ask the locals where the local casinos are hidden, they will tell you.
It was completely hidden, and only certain people could enter and know.
Rather than you are curious about local casinos, it is better to play on your mobile phone only, it will be safer.
I also suggested the same things as you to playing gambling from his mobile phones and in the hotel so no one will know. But he needs to be careful when ask the locals about the local casino. That is because not many people know that places and besides that, the undercover police will be around there. That is why he needs to be careful.
Indonesia prohibit gambling so that is normal if their government blocked DuckDuckGo in Indonesia. That is because they don't wants to see their citizen find a casino using that search engine. But that will not stop those people to use the other search engine.
Yup.
They have probably been blocked due to the activities of their citizens but people nowadays are wise when it comes to these matters. They'll buy VPN or will use any other tools for browsing and continue whatever they're doing to their customers. Whether it's gambling, work related or anything. But at least with the Indonesian government, they've made their own ways of dealing with it through imposing a ban or blockage of duckduckgo. AFAIK, they have a new president so this could change overtime but if not, there won't be any need to modify its decisions.
Using VPN is the option for those who wants to pass the blocked by their government. With free or paid VPN, they can still visits the site they want without any problem. if they can not access one casino, they will search for the other casino and they can find it easily.
The Indonesian government need hard work and serious to imposing a ban or blockage of something that illegal in their country. They need to monitor every ISP's in their country and that will not easy to monitor all people who use Internet.
