If you can not find enough reviews, that means the site is not too popular among the other gambling sites, so it is better to search for the other sites and start writing a review.
It has been almost a week since @OP wanted to write a review for that site, but he has not come back here and told us if he finished writing the reviews or considered writing the other gambling sites.
As I read that many of us do not become aware of the site, I think the site is not recommended for us to play and we can skip for a while to search for the other sites.
After all, we can go back to our favourite sites and continue playing gambling.
