The forum is more reliable than any other source, at least here we can read real comments and not those that are only paid by the gambling site as their way to market to clients. here also, if they will not solve any complaint, that would affect their reputation and it will very visible as DT members will likely tag them for that.
You are right and I agree with you that forum is the best reliable source to know which gamble site we should use and which we should not. From this platform we are able to understand which users are commenting perfectly and which are advocating a gambling site to promote a gambling site. Only newbie account and account with negative trust can post false information others will not do that ever.
I have visit the review site posted by Op . they listed many gambling site on there web page . and they put rating is fine but some scam site also they listed there and give them good ratings. it seems they list site and put rating by money . Which company give them good money they give them good ratings. I do not trust that rating site . I mean this forum is better source for choice trusted gambling site
