The level of online Spanish-language antisemitism remains far higher than it was before October 7, 2023, revealed the new annual report into Online Antisemitism 2025, by the Web Observatory. The research was carried out in conjunction with the Latin American Jewish Congress, the World Jewish Congress, and other Latin American Jewish organizations.
The report was based on the analysis of more than 118 million pieces of content, primarily in Spanish, collected across seven digital platforms.
Antisemitic content was found to be the highest overall on X, with Jew-hatred accounting for 20.68% of all monitored content. Spain had the highest amount of antisemitic content, followed by Uruguay, Colombia, and Mexico (in that order).
This was followed by Facebook, where 14.98% of analyzed comments were classified as antisemitic, making 2025 the year with the highest proportion of antisemitism on Facebook since data collection began.
After the ceasefire, the percentage of antisemitic content on Facebook fell by slightly more than three percentage points, and the daily volume of hate content dropped by nearly 50%. X also saw a decline.
Even so, this decline in both was not enough to return to the levels seen before October 7, 2023.
In comments on digital news websites, antisemitism reached 15.16%, placing it above Facebook and second only to X. The phenomenon here remains significant and strongly linked to international events, since 70.19% of antisemitic comments were concentrated on articles related to Israel, especially articles connected to the war in Gaza.
Post-ceasefire antisemitism numbers
After the ceasefire, antisemitism declined slightly (just over two percentage points and returned to levels similar to those observed before the beginning of the war. The report said this suggests greater dependence on media coverage cycles and less structural entrenchment than on platforms like X or Facebook.
Regarding countries, Uruguay saw the highest proportion of antisemitic comments on digital news sites. Although the volume overall was low, more than a quarter of the comments were antisemitic in nature. Regarding the media in which discriminatory content is found, the following stand out: Montevideo Portal (Uruguay), Metrópoles (Brazil), BioBio (Chile), and Subrayado (Uruguay), whose user comments are above the general average level of antisemitism. A particular case is Montevideo Portal, which, for the fifth consecutive year, is the media outlet with the highest percentage of hate comments toward Jews.
On YouTube, the report saw two different patterns emerge when separating search results from video comments. In video comments, antisemitism measured 11.58%, lower than on X, Facebook, and digital news sites, but still significant. After the conflict ended, antisemitism declined considerably, and in November and December, levels fell below the annual 2025 average. For YouTube search results, however, the report noted a slight increase in antisemitic content after the ceasefire.
The lowest levels of antisemitism in the entire analysis appeared on Google, with an annual average of 3.92%.
This meant that Google was once again the least exposed environment for antisemitic content among all platforms studied.
Unlike social media platforms, the report said Google showed a more stable pattern, less driven by direct interaction and fast-moving events, although still influenced by the prominence of the Middle East conflict in news coverage.
The report's comparative analysis found that digital antisemitism was concentrated most strongly in platforms that are more open, more viral, and more designed for immediate interaction.
It also found (considering year-to-year comparisons) that the conflict in the Middle East did not create the phenomenon of online antisemitism, but rather "intensified trends that already existed and raised society’s tolerance threshold for hostile discourse."
Rapid spread of fake news
The report also raised a major concern about how the rapid spread of fake news, disinformation, and automated bot accounts can propagate antisemitism.
The spread of automated accounts, or bots, has transformed social networks from spaces of human interaction into complex algorithmic battlefields, the report said.
In turn, this allows for the dissemination of disinformation, such as antisemitic conspiracy theories.
"Modern antisemitism is now a narrative that no longer needs specific events to express itself; it has become normalized as part of the digital environment," the report said.
"Within this system, Jews are expelled from the category of “fellow human beings” and transformed into objects of ideological consumption."
