A report from the European Union Agency for Fundamental Rights (FRA) in 2024 shows that as many as 90% of Jews encountered online antisemitic content in the previous year. Additionally, 55% of them encountered online incitement to violence. Therefore, the antisemitism fighters are addressing their open letter to the companies behind the worlds largest social media companies: Meta (Instagram, Facebook, and Threads), ByteDance (TikTok), YouTube LLC (YouTube), and X Corp. (X).

''These companies must realize that online antisemitism has consequences in the offline world and can lead to discrimination and violence against Jews,” says Eddo Verdoner, National Coordinator for Combating Antisemitism (NCAB) and initiator of the open letter. ,,The numbers are shocking and the number of incidents continues to rise. Social media companies must take action now.”

In the open letter, the national coordinators and special envoys identify various risks, such as the operation of algorithms that increasingly place extreme antisemitic content on users timelines. The dangers of AI systems that are based on existing antisemitic prejudices and thereby reinforce them, the so-called ‘confirmation bias’, are also addressed. They therefore call for, among other things, the appointment of sufficient experts who can assess antisemitic content, stricter content moderation on social media, and more transparency about, for example, the extent to which antisemitism occurs on the platforms.

Verdoner calls for decisive action: ''Social media companies still have a long way to go. We strongly urge them to ensure that there is no place for antisemitism on their platforms.''

We are Special Envoys, Coordinators, and Commissioners responsible for Monitoring and Combating Antisemitism. Appointed by governments and international organisations, we dedicate our efforts to counter antisemitism in our own countries, regions, and around the world. We write to you out of grave concern about the spread of antisemitism on your platforms.

Antisemitism is on the rise, both in the online and offline world. It is crucial that online platforms take their responsibility in ensuring a safe online space. Antisemitism online has real world consequences and can lead to radicalisation and violence. According to a survey published by the European Union Agency for Fundamental Rights (FRA) in 2024, 55% of Jews had encountered online incitement of violence against Jews in the previous year. These shocking numbers prove that it is of the utmost importance that online platforms take immediate action to combat online antisemitism.

We would like to highlight a few areas of particular concern. Firstly, we are worried about algorithms that allow for the continuous affirmation of posts containing harmful content such as Holocaust denial and violence against Jews. In particular, we believe online platforms should be extremely alert about the potential negative consequences of AI due to its tendency to absorb and amplify biases. Secondly, we alert you to the fact that antisemitism can be hard to identify due to its many forms. Therefore, it is important that online platforms have the appropriate expertise to identify antisemitism, and stay informed on evolving trends. Lastly, we are deeply concerned that hate speech, such as antisemitism, is not sufficiently moderated due to overreliance on AI, community notes, and decreased measures.

The European Union (EU) has made great strides with the regulation of online hate speech through the Digital Services Act (DSA), and the revised Code of conduct on countering illegal hate speech online. We urge for the immediate and full implementation of the DSA and the Code of Conduct within the EU and for the implementation of the same action and values outside of it, since antisemitism knows no borders.

Therefore, we urge you to ensure that antisemitism has no place on your platforms by finding solutions and taking concrete measures, including:

• Make sure content moderation is effective, in line with the laws in the territories of the respective signatories such as the DSA. Moderation must always be supported by human review.

• Adhere to legally mandated compliance standards related to hate speech and relevant laws in the countries and regions in which you operate.

• Use effective measures to promptly remove harmful content that promotes hate and violence against Jews and others.

• Increase the transparency of underlying algorithms, moderation decisions, and the prevalence of antisemitism on online platforms. For example, by following the revised EU Code of Conduct’s recommendation of publishing country-level data broken down by the internal classification of hate speech.

• Use AI and algorithms carefully to ensure they do not perpetuate antisemitic and Holocaust distorting and denying content.

• Make sure that there is enough expertise and capacity to classify antisemitic content and determine the appropriate actions.

Through our combined strengths we can tackle online antisemitism. In the context of this letter, we would like to initiate a conversation, and will be in touch to set a date for this purpose. Thank you for taking note of our concerns and we look forward to your response.
