Slightly off topic, but the profusion of weird prop bets on sports is a path toward quiet match fixing that we may never be able to roll back. I'm seeing this in e-sports already, where players can still try hard to win but also "accommodate" gamblers who are betting on odd metrics like over/under on total kills, etc.

I think banning of advertising on various things is entirely reasonable approach. Like in Europe prescription drugs can not be advertised to consumers. And I think that is sensible.
