Yes, streamers should want to do something like that to avoid a bad reputation in the future. If there are streamers who share their reference threads to scam casinos, they must receive punishment either from social media where they promote their casinos or from the government for misleading the public. But it seems this has not been done optimally because many streamers are still promoting shady casinos. And unfortunately, the audience is also less wary of watching and choosing a casino.
But in fact there are lots of streamers who don't care about their reputation in the long run so they share shady casino references and all this is done just because there is a bonus of some money which is quite profitable, in this era I not surprised that many people are risking their good name for some money in their pocket.
What is a concern is the lack of knowledge in the gambling industry so that people cannot sort out which casino references are truly trusted and which casinos are shady.
But I'm sure that over time references to scam casinos can be overcome so that circulation can be reduced, especially since there is a legal authority that regulates the gambling industry.
