the current problem is that when someone goes to google to do research they will find many casino review sites but they are sites of people who because they were paid will write good things about the casino even if the casino is a scam, that's why many people are still using scam casinos. and only after being tricked and robbed and people discovering this forum
Going to review sites is not and has never been considered doing research. Its a lazy way to buy into a scam. Someone, in this case, a third party review is going to tell me which casinos are best? Sorry Thats not going to work. I would not trust them to tell me the truth but rather try to sell me their endorsed scam.
I don't really know that market very well, but I think you are exaggerating a bit. If a review site gives positive reviews of scam sites, it will soon lose credibility.
The most normal thing is that it is biased towards some sites with which it has agreements but which are legitimate, so it generates traffic to those sites and receives revenue.
In my case I have never used review sites. I prefer to inform myself on the forum and try it myself.
