A network of suspected bot accounts systematically amplifying New York City Mayor Zohran Mamdani and his allies on X has reportedly been traced to City Hall internet infrastructure, triggering calls for federal and municipal investigations.

The World Zionist Organization’s Department for Combating Antisemitism presented findings from cyber experts who examined IP information and patterns of activity across dozens of suspicious accounts. The experts say they are “100% sure” the IP addresses they examined could be traced to City Hall infrastructure. The underlying IP data and technical methodology, however, were not published, and the findings do not establish that Mamdani, his staff or other city officials created, directed or funded the accounts.

Investigators identified what they described as highly unusual behavior across dozens of accounts, with the WZO estimating that the broader network could include hundreds. Some accounts reportedly produced more than 500 posts per day, while extreme cases surpassed 800 or 900. Several showed repeated-sharing rates approaching 100%, little or no original content and minimal personal activity.

Much of that activity centered on posts from Mamdani’s official account, municipal accounts and political allies. Researchers said the suspected network appeared to rapidly amplify posts immediately after publication, potentially helping trigger additional algorithmic exposure and engagement from real users.

The scrutiny comes amid escalating tensions between Mamdani and supporters of Israel. In a recent video, the mayor acknowledged that New York City does not have the legal authority to arrest Prime Minister Benjamin Netanyahu under the International Criminal Court warrant, but continued to call Netanyahu a war criminal and urged federal authorities to act. Netanyahu subsequently accused Mamdani of “fomenting hate.”

The WZO is now seeking further scrutiny of the alleged amplification operation. Yifat Ovadia-Luski, who heads its Department for Combating Antisemitism, warned that “today’s antisemitism begins online and then moves into the streets,” and called for U.S. federal authorities to investigate.

Separately, the National Jewish Advocacy Center said it is referring the matter to New York City’s Department of Investigation and Conflicts of Interest Board and seeking access to City Hall server logs. City ethics rules explicitly prohibit public servants from using city time or resources, including computers, email accounts and phones, for political campaign purposes. Whether any such violation occurred here remains unproven and would depend on investigators establishing who operated the accounts and for what purpose.
