  • Online antisemitism in Spanish-language content remains significantly higher than pre-October 7, 2023 levels, according to a new report.
  • X (formerly Twitter) recorded the highest proportion of antisemitic content at 20.68%, followed by Facebook and digital news websites, with Spain showing the most antisemitism.
  • While antisemitism declined on some platforms after a ceasefire, it did not return to pre-war levels, indicating a strong link to media coverage cycles for news sites and a more embedded issue on social media.

A new annual report reveals that online antisemitism in Spanish-language content remains substantially elevated compared to pre-October 7, 2023 levels. The "Online Antisemitism 2025" report, a collaboration between the Web Observatory, the Latin American Jewish Congress, and other Jewish organizations, analyzed over 118 million pieces of content 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.

X, formerly Twitter, emerged as the platform with the highest concentration of antisemitic content, accounting for 20.68% of all monitored material. Spain registered the highest volume of antisemitic content, followed by Uruguay, Colombia, and Mexico. Facebook also showed a significant problem, with 14.98% of analyzed comments being antisemitic, marking 2025 as the year with the highest proportion since data collection began.

Spain had the highest amount of antisemitic content, followed by Uruguay, Colombia, and Mexico (in that order).

Following a ceasefire, both X and Facebook saw a decline in antisemitic content. On Facebook, the percentage dropped by over three points, and the daily volume of hate content decreased by nearly 50%. However, these reductions were insufficient to revert to pre-October 7, 2023 levels. Antisemitism on digital news websites reached 15.16%, second only to X, and was strongly correlated with coverage of Israel and the war in Gaza, with 70.19% of antisemitic comments appearing on related articles.

Even so, this decline in both was not enough to return to the levels seen before October 7, 2023.

The report noted that the post-ceasefire decline on news sites, returning to pre-war levels, suggests a greater sensitivity to media cycles compared to platforms like X and Facebook, where the issue appears more deeply entrenched. Uruguay showed the highest proportion of antisemitic comments on digital news sites, with over a quarter of comments being antisemitic on some outlets like Montevideo Portal, which has consistently shown high levels of hate comments.

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.
