A recent report on online antisemitism reveals a marked increase in Spanish-language antisemitic content across major digital platforms in 2025, significantly exceeding levels recorded prior to October 7, 2023. The study, conducted by the Web Observatory in partnership with the Latin American Jewish Congress, the World Jewish Congress, and several Latin American Jewish organizations, analyzed over 118 million pieces of content primarily in Spanish, collected from seven digital platforms.
The examination identified X (formerly Twitter) as the platform with the highest concentration of antisemitic content, where nearly 21% of the monitored material expressed Jew-hatred. Spain was the country with the most antisemitic content overall, followed by Uruguay, Colombia, and Mexico. Facebook also showed a significant presence of antisemitism, with almost 15% of analyzed comments classified as such, marking 2025 as the year with the highest recorded rates on the platform since the study began.
Following the 2025 ceasefire in the Israel-Hamas conflict, antisemitic content on Facebook declined by just over three percentage points, and the daily volume of hate-related posts dropped nearly 50%. Similar decreases were observed on X, though these reductions did not bring the levels back to those recorded before October 7, 2023.
Digital news websites also recorded notable antisemitism, with 15.16% of comments categorized as antisemitic, surpassing Facebook and second only to X. This form of online hatred was strongly linked to media coverage of international events, as over 70% of antisemitic comments appeared in articles related to Israel and the Israel-Hamas War. After the ceasefire, antisemitism on news sites decreased slightly and returned to near pre-conflict levels. Uruguay reported the highest proportion of antisemitic comments on these sites, with some portals such as Montevideo Portal—which has held this distinction for five consecutive years—exhibiting particularly elevated hate comment rates.
On YouTube, the report identified two distinct patterns: antisemitic comments under videos occurred at a lower rate (11.58%) than on X or Facebook but remained significant; this volume diminished substantially after the conflict ended, dropping below the 2025 average in late 2025. Conversely, search results on YouTube showed a slight increase in antisemitic content following the ceasefire. Google’s search environment demonstrated the lowest levels of antisemitism across all platforms analyzed, with an annual average of 3.92%, reflecting a relatively stable pattern less influenced by rapid events or user interaction.
The analysis underscored that digital antisemitism tends to concentrate on platforms that facilitate rapid, viral, and interactive content dissemination. Researchers emphasized that while the Israel-Hamas conflict intensified existing trends in online hate speech, it did not originate the phenomenon. The report further highlighted concerns about the role of fake news, disinformation, and automated bot accounts in amplifying antisemitic narratives, transforming social networks into complex algorithm-driven environments where such hate can flourish.
According to the report, modern antisemitism has become normalized in the digital landscape, often detached from specific events. It noted that Jews are increasingly portrayed not as fellow human beings but as ideological targets within hostile online discourse, reflecting a troubling shift in how antisemitism is expressed and perpetuated across social media and digital spaces.
