I understand you until the point where you contradict yourself. You might want to clarify what you meant by "I don't follow any site to choose casino sites" and "I choose a reliable casino site based on their reviews." For me, you will have to follow sites if you would review casinos as you can't do it all by yourself.
I believe you missed the part where he said "I only use the casino sites on this forum"

What he meant is that he only trusts reviews posted on bitcointalk.
Anyway, I advice him to be also careful about reviews he reads on this forum as some casinos hire shill accounts or create new accounts in order to write fake positive reviews.
