In the days since Hamas’ attack on Israel left 900 dead, San Francisco-based X (formerly known as Twitter) has spread disinformation about the conflict while recommending accounts that explicitly traffic in antisemitism, even garnering a warning from European regulators.

Elon Musk’s engagement with the disinformation around the attacks comes weeks after he defended himself against accusations of antisemitism — after spending months amplifying anti-Jewish conspiracy theories and screeds — during an X event alongside prominent right-wing Jewish personalities.

According to Media Matters, a left-wing watchdog of conservative media, there have been at least six misleading videos that earned millions of views shared by X Premium subscribers with verified blue checks. Other accounts impersonated news outlets and official entities, receiving hundreds of thousands of views, including one impersonating the Jerusalem Post claiming Prime Minister Benjamin Netanyahu was rushed to the hospital.

Musk further personally recommended accounts called @warmonitors and @sentdefender. Both accounts have a history of spreading disinformation, with the former frequently posting antisemitic slurs and condemning “the Zionist regime.”

Musk further engaged with a tweet falsely alleging that “mainstream media has shown more war footage of Israel/Hamas in the past two days than we have seen of Ukraine in the past two years,” and engaging with an Islamophobic conspiracy theory about the negative impact Muslims are having on Sweden.

X’s Trust and Safety Team said Monday it was attempting to curb the spread of disinformation, saying “As the events continue to unfold rapidly, a cross-company leadership group has assessed this moment as a crisis requiring the highest level of response.”

It further noted it removed “removed newly created Hamas-affiliated accounts” and was working with the Global Internet Forum to Counterterrorism (GIFCT) to “try to prevent terrorist content from being distributed online.”

Musk recently linked Israel’s “desire for retribution” against the Palestinians with the desire to seek retribution against those propagating antisemitism on the platform. “You have this endless cycle of retribution,” he said, adding much of his work is motivated by “can we turn an antisemite into someone who is at least neutral, if not pro?”

“If someone does express antisemitic views within reason, I think you do want that out there so you can hear the counterpoints,” he added.

“It’s horrifying but unsurprising that some are exploiting the bloodshed in Israel to launch false and misleading attacks against President Biden and score cheap political points. We know that when disinformation and conspiracy theories thrive, so does antisemitism, hate, and extremism,” said Amy Spitalnick, CEO of the Jewish Council for Public Affairs.

“This should be a moment for moral clarity and unity — and those who exploit brutal murder and kidnapping to further their own careers are no friends of Israel or the Jewish people,” she added.
