At first, I thought it was a new gambling site coming to the forum but only found out that it was just a review. Assuming you haven't done reviews for others in the last I would have thought this was a paid review because it's odd to see a newbie account just pop out of nowhere and start to review an unknown site here.
P.S. Throughout the forum - this site has been mentioned only 12 times.
Actions such as this often suggest that but, I don’t mind the users thoughtfulness of having to share a review of the sites he gambles with and though, there isn’t any exact rule that forbids site not on the forum to not get mentioned here, it’s important you know that, sites on the forum are more given precedence. That’s because, they always have a representative on here so, the extended support line could take and address complaints as they arise.
Hence, if OP is that enthusiastic about this Bookielink, you could as well see them on here.
