The government earn a lot of money from gambling and for the government to put an end to it, it will be very hard unless the Senate decided to take it personal and create law that will be ban gambling ads. If the government have to ban gambling ads then there will be a need for them to ban gambling too so everything will end like that and casinos will not find a means to advertise there business to the public. That is the only way gambling ads can be ban when gambling activities are ban to so that people will not go and look for casinos to use and make bets. Could this be possible?
Government is the one who benefits all of it, they can earn taxes and use it in either funds or personal use . Ads are everywhere now and it can't be avoided , social media platforms are okay with it, they can earn a lot as well . It is a win-win scenario for both of casino owners and social media owners. You cannot control things that is being cannot be controlled, gambling is a business too.
