Like many other news websites, Common Dreams has been plagued by inflammatory anti-Semitic comments following its stories. But on Common Dreams these posts have been so frequent and intense they have driven away donors from a nonprofit dependent on reader generosity.

A Common Dreams investigation has discovered that more than a thousand of these damaging comments over the past two years were written with a deceptive purpose by a Jewish Harvard graduate in his thirties who was irritated by the website's discussion of issues involving Israel.

His intricate campaign, which he has admitted to Common Dreams, included posting comments by a screen name, "JewishProgressive," whose purpose was to draw attention to and denounce the anti-Semitic comments that he had written under many other screen names.
