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.
It does not only happen within the gambling community or those streamers who like to gamble for their audience. Within the common streaming community it had been several dramas and scandals regarding the biggest personalities of Youtube and Twitch.
For example, some days ago I saw some news of a famous female streamer shamelessly snorting ground pills as if it was cocaine, she has doing it in front of a camera, by the way.
Adding the gambling aspect to that community can only result in more drama and tasteless situations, in my opinion.
Regular streamers and gambling ones are definitely not for everyone.
