By contrast my impression of Zero Hedge has been that they are constant economic contrarians. If mainstream media is touting the strong economy, Zero Hedge posters are writing about how fiat currency is unsustainable and how the long-term trend low interest rates is creating a bubble. I do agree the sources of their article range from "I think I heard somewhere" to "based on this Bloomberg data", it's all over the place. But I don't think I've ever seen anything that I would call insidious.
Fair disclaimer that I follow Zero Hedge on Twitter, for much the same reason I follow CNBC: I need a perma-bear to balance out the perma-bull.
