Dette er vel det man kaller astroturfing?
In politics and advertising, the term astroturfing describes formal public relations (PR) campaigns which seek to create the impression of being a spontaneous, grassroots behavior. Hence the reference to the "AstroTurf" (artificial grass) is a metaphor to indicate "fake grassroots," or sometimes "fake environmentalism."
