Apart from being a self-deluded moron, Koobee Wublee is a
well known troll with a well known and very specific agenda.
He has been around for years. Professionally he is a retired
aerospace engineer.
His previous name was Australopithetus Afarensis.
Before that he was Scholarly Fungi and Time Traveler.
When he stopped posting as Australopithetus he
admitted also having been Lordly Amoeba, Ibn Battuta
and Marco Polo.
For a little overview of his statements:
