Columbia University’s most radical anti-Israel group has finally found itself digitally homeless.

Columbia University Apartheid Divest (CUAD), which boasts over 40,000 followers, was banned from Instagram on Monday after publishing a post targeting Barnard College, Columbia’s sister school, declaring it would be “the first domino to fall” in their anti-Israel campaign against the university. The message was accompanied by imagery including inverted Hamas propaganda red triangles, figure wielding a Molotov cocktail, and included violent threats toward university leadership.

The post prompted Barnard president Laura Ann Rosenbury to implement emergency security measures on Monday, restricting campus access to ID holders only.

“Inflammatory posts with violent imagery and specific calls for action against the Barnard College community have been circulating on social media,” Rosenbury told New York Jewish Week. “Any statements that advocate for violence or harm, including the destruction of property, are a direct violation of our code of conduct and are antithetical to the core principles and mission of Barnard.”

CUAD’s rhetoric has grown increasingly violent since organizing last spring’s pro-Hamas demonstrations.

Last week, CUAD began circulating a campus newsletter dubbed the “Columbia Intifada,” a name inspired by the Second Intifada against Israel that saw waves of suicide bombings claim the lives of approximately 1,000 innocent people. In October, the group openly endorsed “armed resistance by any means necessary,” which prompted Congressional investigators to release a damning 300-page report on Columbia’s handling of campus antisemitism.

Over the summer, Columbia’s other antisemitic body, “Students for Justice in Palestine,” was kicked off Instagram for violating Meta’s “Dangerous Organizations and Individuals” policy. American families who lost loved ones on Oct. 7 are pushing U.S. Attorney General Merrick Garland to investigate SJP for what they describe as a “coordinated effort to justify the massacre.”

“American campuses should be safe spaces for education, not platforms for spreading hate and violence,” the Shurat Hadin Israel Law Center, which represents the victims’ families, wrote on Facebook.
