Well, it is easier to rely on reviews and opinion from people here, since we have a pretty established reputation system, which helps to consider or completely cross out opinions. Even though nowadays it is almost impossible to trust classic review sites, I believe there are chances for those platforms to redeem themselves by enforcing some kind of policy and system similar to what we got here in Bitcointalk.
On the review site, there is no review of the reviewer and that is the problem. Anyone can be hired to make a lot of reviews for a gambling site. But here on the forum we have a reputation system and we have to work hard to rank up that's why we usually do not take any part/support any scam. As a result our feedback regarding any gambling site and currency exchange site is perfect.
