The image above is taken from the home page of the conspiracy article you linked to... and probably shows how much weight we should give to the conspiracy being written about. Here is the primary paragraph of the Zetatalk site:
ZetaTalk leads you through the vast amount of information being relayed by the Zetas in answer to questions posed to their emissary, Nancy. The ZetaTalk answers cover such subjects as portents of a Pole Shift and how this relates to the Transformation in process; how life in the Aftertime following this shift will be different from today; the self-centered or service-minded spiritual Orientation of humans as well as aliens from other worlds and how inadvertently giving the Call to aliens can put you in touch with one group or the other; how Visitations can be more easily interpreted when spiritual orientation is understood; how visitors from other Worlds are watched by the Council of Worlds, which has set Rules regulating their behavior; why we are only gradually getting acquainted with our visitors from other worlds, and what will allow the Awakening to occur faster; to what extent the Government is aware of and interacting with the alien presence; the true nature and reason for the Hybrids being developed by the Zetas to merge the best from both Zetans and Humans; why aliens can disappear and move through walls, and what both physical and spiritual Density changes will be like in the future; what the Zetas have to say about our Science theories; what the Zetas as students of human nature have concluded on what Being Human means; and straight ZetaTalk about our Myths.
The space aliens are being channelled by "Nancy". Right. Sure.
