Influencers being bluntly paid actors that advertises casinos and encouraging gambling at its finest is one thing, but using elements that could impact the minors and innocents is another level. But then how can we do something that would restrict companies and influencers from using such, because we all know that for as long as its effective and they are gains on it, they will continue to do so. Maybe we could try calling out those influencers and casinos, collectively, to get their attention and also bring public’s eyes onto them and their actions.
There no need for such actions. Despite advertising law regulates such cases without proper efficiency on Youtube, i think in near future (1-3 years) everything will change dramatically. Not only you (and me) were being annoyed by such dishonest promotions. As i heard new regulations on Youtube is near to come

I wonder how the Youtuber will be if Youtube makes their rule strict than before. Maybe they will limit all related things and tolerate if the influencers spread something that can cause people's lives to become unusual. We are annoyed by those promotions but we can not do anything but luckily, we can report the ads if we think they can or have already broken the rules so Youtube can warn them.
