What screenshot are you talking about in particular?
Cus after reading your comment, I've gone to the first page to check the two screenshot the op posted in his first post. And I found no where it was written that the op should review the casino on any forum and get rewarded, if you think I am missing something here, (which I want to believe I am for now), then please point me to the particular shot you are talking about..
But then again, even if the website said so, I still do not believe that op does not have any relation with the site, owning a website gives you access to everything on it, it cost nothing for op to login to the database of the site and update the site with that information, so as to have something to defend himself with after reading all the comment here accusing him of being the owner of the site.
It's about this screenshot:
https://ibb.co/xC5CrCfHe shared it
here, and it clearly shows that he is asked to actually do a review in any public forum and he chose to do it on this forum. He is probably not being backed up or anything and no one specifically say that he is not related to the casino or anything, it's just about what might be true as well.
If he is actually somehow related to the casino and its team and is only here to promote the casino this way, it would probably be better for the team to properly announce the platform in the forum and they could possibly get a lot of active users from here.
