Haverford Professor Charged With Federal Cyberstalking Over Antisemitic Threats Against a Jewish Colleague

Alums for Campus Fairness (ACF) is monitoring the federal cyberstalking case against Haverford College assistant professor of religion Guangtian Ha, who is accused of using anonymous social media accounts to threaten and harass a Jewish colleague and his family.

According to the U.S. Attorney’s Office for the Eastern District of Pennsylvania, Ha was indicted on a federal cyberstalking charge for allegedly sending about 50 antisemitic and threatening messages from at least four anonymous X accounts between October 9, 2025, and May 20, 2026. Several posts allegedly included the family’s home address, and one referenced the colleague’s minor child. A subsequent government filing catalogues 54 posts, including repeated invocations of the Holocaust and the extermination of Jews. Prosecutors also allege the messages included photos of the colleague’s house, and court records cited by The College Fix state that the messages caused his spouse and children to leave their home. 

Ha was arrested following an FBI investigation and has pleaded not guilty. He will remain in custody until his trial, scheduled for December 3, 2026, after a judge cited flight-risk concerns. Haverford has placed him on administrative leave. Ha faces up to five years in prison if convicted.

The case has raised urgent questions about antisemitism in higher education and the responsibility of college leadership to ensure the safety of Jewish faculty and other members of their communities.

Jonathan S. Quinn, a Haverford alumnus, called on Haverford’s Board of Managers to commission an independent investigation into the College’s handling of the situation:

“As a Jewish and Zionist Haverford alumnus—and the parent of a Haverford graduate—I found the government’s filing chilling. It catalogues 54 posts allegedly directed at a Jewish colleague and his family, including publication of his home address, references to his child, warnings that security cameras would not protect him, and repeated invocations of gas chambers, the Holocaust and the extermination of Jews. The government further states that Professor Ha admitted operating the threatening accounts and that forensic evidence ties his phone to the newest account.

“Professor Ha is entitled to due process. But if proven, this was not merely offensive speech or criticism of Israel; it was a sustained campaign of antisemitic terror. Placing him on leave was necessary, but it cannot be Haverford’s final response. The Board should commission a genuinely independent investigation into what the College knew, when it knew it and whether administrators responded appropriately—and make the findings public to the fullest extent permitted by law. Haverford’s professed values of trust, concern and respect require truth, transparency and accountability.”

ACF will be watching the criminal case, whether Haverford’s Board of Managers commits to an independent review of what the College knew, and how the College protects Jewish and pro-Israel members of its community.
