Algorithms of the Big Tech Reich: The Evolution of Online Antisemitism Since October 7
In the face of the current wave of hatred against them, Jewish communities all across the world share a fundamental and timeless desire: to be seen and treated as human beings.
Antisemitism, however, has historically sought to strip away the perception of Jews as human from the fabric of religions, societies, and international forums.
Today, the assault on the perception of “the Jew” as a human is being executed through supercharged algorithms at an unprecedented scale.
In the year following the October 7 Hamas massacre, data from the major social media platforms revealed a troubling escalation in online antisemitism.
Trending anti-Jewish narratives online have moved beyond classic tropes like disdainful jokes or conspiracy theories about Jewish control, and have morphed into overt hostility, calls for violence, and a dehumanization of Jews as inherently evil. This is not merely an extension of past trends; it represents a perilous escalation in anti-Jewish rhetoric.
To effectively prevent purposeful widespread violence against Jews and safeguard national security in any Western democracy, social media reform and legislation requiring algorithmic transparency is crucial.
Recognizing the need for proactive solutions until the legal impasse on social media accountability was breached, I founded CyberWell, a nonprofit organization that launched the first open database of online antisemitism in 2022. Our efforts provide a unique multilingual analysis of online Jew-hatred, following the guidelines of major social media platforms. Today, we are official Trusted Partners of both Meta and TikTok, and share real-time alerts and digital policy compliance analysis on online Jew-hate in both English and Arabic, with additional platforms we monitor. Our goal is to increase the enforcement and drive the improvement of content moderation policies across the digital space. Our most recent report unpacks the evolution of online antisemitism in the year since October 7.
October 7 marked an unprecedented hijacking of mainstream social media by Hamas, who fashioned engagement algorithms into tools of psychological warfare. Unlike the slow drip of information surrounding the genocide of Jews that was committed during the Holocaust, the screams and gore of the hunt for Jews and perceived “collaborators” in Israel were broadcast at a massive scale, even to the personal Facebook feeds of those families slain within their own homes.
In the year since these attacks, CyberWell’s monitoring technology detected a 36.6 percent rise in content likely to be antisemitic across social media platforms. Most notably, there was an 86 percent spike in anti-Jewish content within the first three weeks after October 7. This flood of antisemitic content contributed to a significant increase in calls for violence against Jews — rising from 5 percent in the 11 months before the attacks to 13 percent of verified anti-Jewish content post-attack. Alarmingly, 61 percent of verified antisemitic content in Arabic in the weeks following October 7 justified or supported violence against Jews.
A pattern reminiscent of post-Holocaust denial also emerged immediately after October 7. This time, however, denial narratives were propelled into mainstream discourse through social media algorithms. Our October 7 deep dive report found that a mere 300 verified examples of denial content reached 25 million accounts within just over a month, with X (formerly Twitter) showing the highest engagement rates for such narratives. It is no wonder, then, that even Susan Sarandon denies that women were raped on October 7.
On the anniversary of the attacks, the same cell of anti-Israel influencers identified in CyberWell’s report amplified 10/7 denial that started spreading 10/7 denial narratives as early as October 8, 2023, released a 45-minute documentary further perpetuating this disinformation in violation of YouTube’s policies against violent event denial.
Initially, the most widespread narrative focused on denying the exploitation of sexual violence and rape during the attack; now, it has shifted to claiming that the Israeli state orchestrated the massacre. To date, only TikTok has directly recognized October 7 denial as prohibited content according to its community guidelines.
CyberWell’s data indicates a significant shift in trending antisemitic narratives. Before October 7, the most popular antisemitic theme was the trope of Jews controlling the world or seeking world domination. Post-attack, narratives predominantly cast Jews as the enemy (29.2 percent of verified content) or as inherently evil (21.5 percent). These narratives echo historical prejudices that have justified violence against Jews for centuries—from the Crusades to the Inquisition, to the religious oppression of Jews in Arab lands, and through the horrors of the Holocaust.
Today, algorithms, rather than prophets, religious institutions, or state-controlled media, are the primary amplifiers of this toxicity. The platforms showcase brutal acts against Jews while simultaneously facilitating a denial campaign aimed at dehumanizing them and shifting the blame onto their first line of defense. In this environment, Jews are increasingly viewed as less than human, rendering their suffering unworthy of sympathy and their right to defend themselves irrelevant, if not outrageous.
We Jews are patient zero for social media’s darker impulses. Campaigns against our humanity have long been effective and popular messaging for various overlords throughout history. Now, under the current regime of big tech and in light of the US-elections, we must urgently call for legislative reforms that enhance online safety and demand transparency in algorithms. Our lives depend on it.
