Same thing as everyone has mentioned before, I've witnessed members being disrespected or attacked (even in a passive aggressive manner) by other members for merely airing their personal views on certain readers, that creates a discouraging atmosphere for persons who may want to openly share honest feedback on readers.
Also, the readers themselves target you if they're able to identify your account on their site, I've actually experienced outting a scammer only to have my account shut down by bitwine because of the information I shared here. I have no regrets and the scammer's profile is deleted now but it's hard to freely post with the best of intentions when everything you share here makes you a target or the information that you so share is used against you in a nefarious manner.
The truth is, this site isn't a safe zone to share psychic reviews, it takes a lot of courage and defiance to post anything here and not everyone is up for that. They're probably doing the smarter thing which is protecting their identity/privacy, gathering information on the low and using it accordingly. We're the ones bearing the risk when we post our business up, but that's entirely on us...
