A professor at Haverford College in Pennsylvania has been charged with federal cyberstalking in connection with a campaign of anonymous antisemitic posts targeting a colleague, according to court documents filed Tuesday. Guangtian Ha, a religion faculty member, was taken into federal custody amid allegations that he repeatedly harassed the victim with threatening messages on social media.
Federal prosecutors allege that Dr. Ha posted the victim’s home address, the name of the victim’s infant child, and a photograph of their family mailbox, accompanied by numerous antisemitic slurs and threats. The posts reportedly caused significant fear and distress, prompting the victim’s spouse and their three children to seek refuge with relatives on two occasions.
The victim, described by three sources familiar with the case as a Jewish member of the faculty, has not been named in court papers. Prosecutors maintain that Dr. Ha operated anonymous accounts on the platform X, sending messages such as “Get out of my country. You don’t belong here. Die Führer is coming, rats,” and later, “Remember this. You scums have had it too easy.” In February, according to filings, he warned, “Run. Flee. Leave. Blurring your home on Google Maps and installing a security camera next to your mailbox won’t help.”
Investigators traced the anonymous accounts to IP addresses linked to Dr. Ha’s devices. Following his arrest, the professor admitted to creating the accounts, according to federal prosecutors. No public record currently identifies his legal representation.
Haverford College President Wendy Raymond issued a statement confirming that Dr. Ha, who was on sabbatical and not teaching at the time, has been placed on leave and barred from campus during the ongoing legal process. Raymond expressed deep concern over the alleged conduct, emphasizing the pain it has caused, particularly in light of recent Jewish holidays and the anniversary of the October 7 attacks.
Dr. Ha’s social media activities have drawn prior scrutiny. Last year, his name emerged during congressional hearings addressing antisemitism on college campuses. In May 2025, Representative Virginia Foxx questioned President Raymond about Dr. Ha’s online statements, which included calls to dismantle the state of Israel and equated Zionism with Nazism and fascism. Raymond acknowledged antisemitism as unacceptable while distinguishing it from political criticism of nations or governments.
In August, Haverford settled a federal civil rights lawsuit filed by Jewish students, parents, faculty, and alumni that accused the institution of failing to protect Jewish members from discrimination and harassment. Dr. Ha’s posts under his personal social media accounts were cited multiple times in the suit.
The federal case against Dr. Ha highlights ongoing concerns about targeted harassment and antisemitism within academic environments. The investigation and legal proceedings remain active.
