I think I haven't seen a gambling game ad yet when watching a TV but when some show ends, one of their sponsors can be a casino. On some sports, there might be banners now of a gambling company that are shown.
I still think exposures like these won't get the attention of our child so this is not alarming at all but on your case, limiting those kind of ads may not be enough. What is truly needed there is to not accept such ads but the problem is if the network will agree since they can also earn money on it. Sometimes a company won't care about the sake of other people but what important for them is only their own selves. All you can do for now is to blacklist that channel. I am sure modern TV's has this option now.
Well, in some countries like Colombia and Chile, when you watch sports, especially football, you do see casino advertisements, but on the fields, it is something that you cannot ignore, however, there are casino advertisements and advertisements but that They are fiat casinos, controlled and I imagine they must have much more KYC than what a crypto casino might require, so based on this, I think it would not be bad to put it on a blacklist, because it is advertising, when it was like 4 -5 years old I saw a lot of cigarette advertisements and they were very good and yet as a child for that time it never caused me to smoke, I already knew that it was harmful to the lungs and I didn't pay attention to them, but I did like the announcements.
I have always wanted to see a crypto casino on TV, because that is like promoting Bitcoin, just the fact that they say in the advertisement that it is a crypto type and people start wondering, what is crypto? or what bitcoin is, (for those who don't know) so I don't see this type of thing as bad.
Children are in much more danger now that tablets and phones are available to them so they can do their things and there are many dangers, the most dangerous thing of all, I think it could be casino notices, because there they can enter prohibited places. , where there are pedophiles and sick people, that is dangerous and I think that is the only thing that parents should take care of the children more, instead give a TV because the thing is different, and for me if they can get to many hearings, I don't know Why not, but there are countries, especially in South America, where people watch a lot of TV and now there are many people who have a lot of money and know that these casinos exist, so why not take advantage? Things always go your way.
