Good point. When we ask for regulations, we should understand that many of good stuff can be banned too along the way. I bet there are no dishonest streamers and no scammers on the North Korea's national intranet, called Kwangmyong. But do we need such a thing? I don't think so.
I would add that we all don’t really know anything at all about what is happening with the Internet in North Korea, as well as, in general, how the citizens of this mysterious country for the world community live there. But, I think, of course, Internet scammers become there - it's deadly. However, everyone knows about some hackers from North Korea who mine bitcoins and maybe dollars for their country. 
Yeah, but obviously all those hackers are working for the North Korean government. If you are an independent hacker in North Korea - you dead.
As for immoral advertising, as I recently found out, in general, the advertising market is already 1/3 on TV, and 2/3 on the Internet in terms of the cost of this advertising. At the same time, there is almost no regulation on the Internet and immoral advertising on the Internet knows no boundaries and brakes at all. And whatever one may say, any of us faces it from time to time.
And I have no idea what will happen to the restrictions on advertising when we all move to Web 3.0

I have no idea either. Are we moving to Web 3.0 at all? And if we are, will the internet, as we know it today, be completely abandoned? I mean, you can download any book to your kindle, but people still buy paper books. Let's hope for the best, though. Let's hope in the Web 3.0 will be no "immoral marketing", whatever that means.
I like your idea about web 3.0, but we are still on the stage of the concept, I think. Blockchain offers many opportunities, but to build web 3.0, we have to reset our minds first. Humanity is too centralized and even at those Blockchain dawn times, we have seen centralized exchanges instead of decentralized ones. Decenstralized Internet is looking like a city on the cloud. When it comes to online casinos, the idea of decentralized gambling sites is great, but you should never forget that one day the blockchain itself may be abandoned. If this happens, the casino that is built on this Blockchain will be closed automatically. It looks non-realistc, but with this huge number of blockchains nowadays, this may become true one day.
