It's a seemingly paradoxical situation: gambling is legal, but talking about it is restricted. Imagine a society allowing the activity but discouraging open discussions about it. The reasoning behind the ban, is to curb the addictive nature of gambling. Promotional narratives often focus on big wins, minimizing the risks and potential losses. Imagine positive gambling stories influencing people who wouldn't normally gamble.
The concern about the "contagious" nature of gambling through word-of-mouth or online testimonials is insightful. Hearing about someone's big win can spark interest in others, even those with no prior gambling experience.
I don't think the ban is about discussing it. I think it is about displaying ads about it. There is a difference I think.
Mostly because if they start banning speech, then that's a bad thing really.
But they have banned certain types of advertisements like tobacco, alcohol, etc. I think it's not something new.
