UPDATE:  Read this section of a Wikipedia article about "The One Million Dollar Paranormal Challenge" http://en.wikipedia.org/wiki/James_Randi_Educational_Foundation#The_One_Million_Dollar_Paranormal_Challenge -- it relates to this guide.

There are many legitimate paranormal groups, but there are also many fake paranormal societies.  The fake paranormal groups are made up organizations that exist do so several things. They act as shill bidding rings where people around the world shill bid on each other's items so eBay doesn't catch on. The fake paranormal groups also give fake certification to people selling items which basically is pretending to be customers and posting on the internet to praise themselves while doing the same to bash their competitors. When the fake paranormal groups bash, it's not "I hate these other sellers who I won't name that do this and this" but they will bash people by username and other personal information. (Please note in none of my guides have I mentioned a single name of an eBay seller.)

A real paranormal society isn't a platform to sell paranormal items.  Simply put "paranormal society" into a web search and you will see what I mean.

Beware of any paranormal group that claims to as one such phone group does to "establish a list of trusted sellers that have been identified as legitimate and reputable" because anyone such a group claims to have "reviewed by [their] membership and deemed authentic" are the puppetmasters behind such a group that gives phony evaluations.
