I am not a fan of streaming communities in general for these exact reasons, especially for gambling. I use to follow a couple Youtube streamers who would talk about gambling opportunities, giving helpful tips and what not. But as time went on, I could tell that they were starting to just promote certain platforms and it was clear they were being paid to do so, and didn't necessarily believe in what they were promoting, just getting paid for it. No thanks.
Well, yes there are a lot of streamers like that. It's their way or a part of how they market the gambling website that they are promoting. They have to earn it themselves of being a gambling enthusiast to look professional in front of their viewers and make them believe in everything they say. Even if sometimes their words are just full of nonsense that a real gambler can easily tell they are just talking sh*t.
