And I was shocked: in the photo there was a great guy, but during the streams he behaved like a moron who was let out of a cage. He addressed himself in the third person and reacted violently to every win.
Addiction divides personality, that's for sure.
Besides addicted to gambling, he can lost his minds by talking alone so that should make the audience understand what is the danger of gambling.
Streamers should promote the casino but he must always take care of himself so he must know that gambling gives a big temptation to all. He can use gambling for fun and always reminds that he is work to make money by promoting the casino but not for playing gambling to make money.
On the other hand, talking about promotional shows carried out by streamers, I think it is very unlikely for them to tell the audience about the magnitude of the negative impacts that can be caused by gambling, especially when someone is trapped in a cycle of addiction, because if they tell the audience that, of course the number of viewers who will join will decrease and of course that means the commission they will get from the casino will not be big either.
And that is why most streamers tend to always show very tempting winning amounts, none other than the goal of getting more viewers interested and registering on the site they are promoting.
But of course apart from all that I quite agree with the idea of your last paragraph that he should not make himself a victim of the negative impacts of gambling.
