So is all the advertising run during morning cartoons, and that targets an even younger demo than 13-17 year olds.

Those ads are bad, but instagram and its ilk are quite addictive. If don't think it's ok to turn a large group of children into screen zombies because "ads during cartoons".

Children can't interact with these ads to get into the wheel of more ads targeting their specific tastes. Very different level, and degree.

Yes

And it's frankly disgusting that some countries allow such ads.

What does wad mean? Dead?
