To me, it has always been a red flag to see a casino resorting to artificially manipulate reviews on a site like trust pilot.
But even so, it remains a reference site for people to avoid scams. I say this for the following reason: when I want to evaluate a casino, I search for it on Google, so I don't ignore anything I see. If I see many negative comments on Trustpilot, I consider that a red flag. I don't focus on the positive comments; I even ignore them. I only want to see the negative comments. I count the number of negative comments and carefully read each accusation of scam. Then I check other sites like casino.guro and compare the negative stories posted on Trustpilot with those on casino.guro, this forum, and other sites. This makes it easy to conclude the casino's reputation level and which negative comments are fake and which are true.
