TikTok is acting to block misinformation used to spread antisemitism as part of a broader crackdown on hate speech.

In a blog published Wednesday, the social media firm said it would clamp down on posts about “notable Jewish individuals and families used as proxies to spread antisemitism.”

TikTok, which already prohibits Holocaust denial and hate speech, said it would now target “coded language and symbols”, white nationalism, male supremacy and identitarianism. 

The app will also target material promoting the baseless white genocide theory. Its adherents believe in a Jewish plot to destroy the white race through mass-immigration and forced assimilation. 

Enforcement will remain “an ongoing process” as behaviour continues to evolve on the app, TikTok said. 

The move comes as social media firms face growing calls to do more to tackle hate and misinformation, with Facebook and Twitter both updating their policies in recent weeks.

Karen Pollock, chief executive of the Holocaust Educational Trust, said companies have a responsibility to counter hate. 

“We welcome today’s developments and look forward to seeing these policies implemented to ensure that Holocaust denial, distortion and antisemitism are not welcomed, shared or supported on TikTok.  

“We will continue to work with TikTok and other social media platforms to make sure this is the case,” she said. 

Danny Stone, head of the Antisemitism Policy Trust, said TikTok has a “large and growing audience” and an “equally big responsibility” to ensure its platform is not used to spread hate.

He said the charity was “pleased that the company is seeking to deepen its understanding and broaden its policies” against antisemitism and other forms of racism.

“We look forward to emerging platforms taking similar such actions,” he added.

Tiktok reported last month it had more than 100 million monthly active users across Europe.
