I like review sites that actually show the positives and negatives to each site. Most review sites are just ref sites.
Hahaha...I don't think there are review sites that would not say the pros and cons of the casinos, not even if the reviewer was paid, such would, of course, fake some parts, or should I say be sincere about some parts, at least, so that it would not be so obviously sentimental for people reading it not to suspect it. This is why I see what you just wrote here as pointless, because every review site, especially those that allow real users to post their experiences will always have positive and negative reviews, which makes your point indistinct.
Above all, I urge everyone to locate a review site that would balance things and most importantly truthful about the reviews. I believe such can be gotten from the review site that allows people to share their experience freely, especially forums like this. One can surely locate the right casinos that will be truthful to their service.
