Well they should regulate it so well since somehow we cannot deny the fact that there are lot of minors also watching those big sporting events.
But it should be done thru join efforts by regulators also with the parents guiding their minor childrens and teach them towards what they need to know about gambling especially if they asked question about betting on sports they love to watch.
I also think that they would pay less attention on the logos or ads they see since for sure the focus of young people is on the game and also to the athletes they support.
