The damage has already been done and just banning public promotions of gambling will not be enough in reducing gambling addiction. Public sensitization targeted at young people, even minors should be encouraged so all will know that certain gambling patterns are unhealthy. If the government only stops people from talking about gambling, it won't erase how they feel about gambling.
"Erase" isn’t the right word.. what they should aim for is to minimize. It’s actually fine for a country to have gamblers since gambling isn’t illegal. And even if they do ban it or declare it illegal, that won’t stop the reality that there are always people willing to take the risk and break the rules.
So if the goal is really to control addiction then removing those big gambling billboards is already a good start. I just hope they stay consistent and continue to monitor and go after illegal gambling operators. Also, aside from removing visual ads, they should stop vloggers from promoting gambling platforms as that’s another source that keeps feeding the hype.
