~ Okay so it's democratic and they have the right to do so even doing the immoral marketing stuff. The internet users will just not care about it until the casino had scammed and got some bad reviews already which the warnings will be to avoid them.
But I think it's actually a good sign that the casino has no care for its clients which will one day do scam stuff because from the beginning they are already doing immoral marketing.
But what is the reason for giving such casino bad reviews? Firstly, we can't know for sure whether casino is paying to video blogger, or he's just showing his big wins to attract more viewers to his channel. Secondly, unless it's original casino's slots, which is rare, casino has no control over them, and by itself it can't make you lose(or win). Even slot providers can't do that without breaking the law. So I don't think anyone, except video streamers, should be getting bad reviews in this case.
