It really doesn't matter if there are some of the fake bad reviews by the frustrated gamblers or sometimes deliberately forced negative reviews by other competitive casinos. In both cases, they can be easily overlooked if the casino itself is good and the genuine players are happy there as they will oppose those reviews, or there would be many better statements from them about the casinos.
But having some bad reviews on a gambling casino still damages its image. It makes new users to be skeptic to try that gambling website. Genuine users will oppose but as a new user you will definitely have doubts if you read some negative reviews.
Exactly especially to those people who's not a regular bitcointalk user and just find out those bad information thru research they made. They might somehow got disappointed on the reviews they get especially if they won't see any resolution on the issue.
That's why support presence or community help towards giving proper resolution or counter feedback on the accusation either its legit or simple trolling is helpful. Since for sure newbie readers could read the discussions happening and they would get an idea that the casino is good then they can validate that those accusations posted against them is been solve or either made by those people trying to troll their casino.
