Your approach makes sense, especially considering whether the casino has the balls to start on the forum investing in review campaigns and signatures. I've already mentioned this a few times in other topics. Of course, this isn't a way to guarantee 100% that a casino is trustworthy. You have to analyze the feedback, length of stay, reputation analysis sites like Trustpilot, and whether people are able to withdraw crypto.

Another relevant point is to check whether the casino author or a representative is present on the forum and answers questions and problems that arise on the forum in their ANN and other related topics.
