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. 
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
