That's true, but I was responding to Lunafox, specifically the part where he states that "it is useless to check casino reviews" which I strongly disagree with. While some reviews can be biased and/or poorly written, they're much better than no information at all. And in the very least, they give us a first impression of each online betting site before we do anything else. You should still be doing a lot of your own research, checking things like the overall reputation of the site in question, their licensing and regulation status and if they're offering games from reputable software providers.
You can't believe all the reviews, because paid reviews are very common now. On the other hand, usually if a person likes a casino and everything is OK with him, he does not write reviews, since everything is fine. But as soon as a small problem arises, a person immediately begins to write a lot of negative reviews everywhere.
