Still, you fall again within the realm of trusting a third party about the legitimacy of a third party, it is kind of a redundancy if you asked me. It would be more productive not go to directly for a centralized platform to seek for information about casinos but focus on communities like this one, in which anyone with certain level of experience and reputation could give you their own opinion and appreciation on the casino you are interested in.
I am not implying those websites you talk about and ill-intented or anything like that, but it is not a good practice to completely trust what they say. I have personally seen how good review webpages have been corrupted by services like scam casinos for them to get promoted, since I experienced it, I rather to open a thread in this section and openly ask about a service, instead of reading and review webpage...
Just my two Satoshis, though.
