You are right, every review from websites, influencers and operators is a review that cannot be completely trusted because some of them will receive payment to compile reviews that can influence other people to gamble at scam casinos, they don't care about the reputation of the casino but they will agree to the proposal review when the value offered matches their expectations, so don't trust gambling reviews from outside the forum unless you can analyze some important points yourself to judge the reputation of the casino, just focus every review on the casino in this forum because we assess all aspects without manipulating any reviews because all analyzes are published for the benefit of the gambling community to avoid scam casinos.
I do not think some of them, I think maximum of them provide reviews on websites, YouTube, or somewhere else usually for the payment that they have received. And as they create reviews for the payment they can't create the reality hence they post positive sites of them whether that is correct or not.
