Before using a gambling platform most people try to get details about that site. As a result finally they take their decision by collecting other users review about that specific platform. So you can say that review has been so vital for any kinda online related business just not only for gambling platforms.

I will suggest you to keep an separate section which will contain every gambling platforms official ANN link of bitcointalk (If have) and your site visitors can easily get more details by visiting bitcointalk users discussion through that link.
