Not just that the casino in question does not have an announcement thread on this forum, but op also said in one of his comments that the casino itself suggested to him to review them(the casino) on this forum for extra pay - 😂, how foolish can the rep of this casino be for asking a user to review their casino on a forum where they don't even have an announcement thread, op himself is a big fool to believe that we will believe such a gullible story.
Well, basically if you see the screenshot that OP has shared, they didn't specifically ask him to review the site on this forum, but they suggested that he does it on any public forum and he will get $5 for each referral that he gets which means he probably needed to post his referral link or tell users to sign up using his link, it's probably how they have programmed their referral program structure.
OP might be telling the truth that he is not related to the website because everyone here is doubting him for promoting the casino without having an ANN while the casino has asked him to post a review in any forum and OP chose this one himself.
