Digital antisemitism remains critical, adapting to new propagation methods

Digital antisemitism persists at critical levels, employing new methods of propagation, according to the 2025 Annual Report on Online Antisemitism. Presented by the Latin American Jewish Congress (CJL) and the Web Observatory, the study surveyed over 118 million posts across social media, search engines, digital media, and video platforms in Spanish-speaking regions. The central finding indicates that online antisemitism has not receded to its pre-October 7, 2023 levels, a date marked by a significant statistical surge in hate speech.

Before the Hamas attack on Israel in October 2023, the Web Observatory recorded an average of 4,000 antisemitic messages daily on X. This figure exploded to 200,000 on the day of the attack, with approximately 5.9 million antisemitic contents counted in October 2023 alone. Two years later, the report reveals, the volume remains high, with 4.9 million monthly messages recorded in September 2025. Even after the conflict's conclusion, around a million antisemitic contents were still detected in December, far exceeding historical pre-October 7 figures.

The report warns that the cessation of hostilities in the Middle East did not lead to a proportional decrease in online antisemitism. Instead, a portion of this digital hate has become a stable part of the online landscape, normalized and no longer solely dependent on current events. Researchers noted a transformation in how antisemitism is expressed, often disguised as irony, distorted historical narratives, or disinformation tied to international affairs. Conspiracy theories alleging Jewish control over economic, media, or political spheres remain prevalent and adapt to current topics to attract new audiences.

Classic antisemitism, such as Holocaust denial, constitutes a small fraction of the detected content. On X, it represented only 0.39% of antisemitic posts. The majority, 87.63%, called for Israel's destruction or denied its right to exist, blamed Jews for the Gaza situation, and equated Gaza with the Holocaust or Jews with Nazis. Another 12.76% involved comparisons between Israel or Zionism and Nazism. Investigators also identified a growing strategy of using terms like "Zionist" or "Zionism" as substitutes for "Jew" to bypass platform moderation filters.
