Pleiadian
People from the Pleiades who actually do not exist.
According to Sfath's Explanation, Billy was told as a young boy that by initially using the term Pleiadian, when referring to the origin of his contactors, the fraudsters, fantasists and deceivers who would later claim to be in contact with Pleiadians would and have then been exposed.
Billy Meier and FIGU information is of a different character and that is obvious to any discerning reader.
Billy was told that the Pleiades star cluster in our space-time configuration is too young to support life i.e. uninhabitable, and the Plejares is the true star system from whence Sfath, Ptaah, Semjase and the other Plejaren originate.
Pleiadian community
If you type Pleiadian into Amazon books, 22 pages of books with variations of the word in the title come up. None (few) of them have anything to do with Billy Meier and the information he has given. Same principle applies to a google image search for Pleiadian.
In the early 21st century what began happening is these strange pleiadian websites which had been popping up all over the place, began inserting segments of text from the translations, remixing and adding words like plejaren into the title and body of the text. Obviously this still doesn't legitimise any of it; it continues to still not have anything to do with Billy Meier and the information he has given.
Accreditation
It is true that prior to the publication of his many books decades before, the term pleiadian was barely if ever used. However much of that awareness can be credited to the original investigators and the nature of the information creating a real stir in all sorts of places and a new worldwide controversy which has always been mostly silent for lack of any better way of purveying such information. It built up gradually, along with the various goings on etc., back in the 20th century, which really brought the story to the world. It was then later that the fraudsters, fantasists and deceivers came along, climbed on the bandwagon, as explained previously, just as they knew it would as forecasted, and that is usually how it works of course, they wouldn't have existed prior to that would they. So you can credit Billy Meier for starting the Pleiadian thing, for being originator decades before, but not for any of the rubbish which has nothing to do with any of what he and FIGU has published.
