Twitter has the most antisemitic content of all the social networks, according to a study.  

Researchers looked at 382,000 antisemitic posts on social media in 2016 and found nearly two-thirds of them appeared on the site.

Eleven per cent were posted on Facebook, six per cent on Instagram and two per cent appeared on YouTube.

The study, carried out by the World Jewish Congress, applied the International Holocaust Remembrance Alliance’s definition of antisemitism in analysing the posts.

Robert Singer, WJC’S chief executive, said: “We knew that antisemitism online was on the rise, but the numbers revealed in this report give us concrete data as to how alarming the situation really is. We hope this serves as a wake-up call to all internet forums to maintain moral standards, rid themselves of offensive content, and make the digital world a safer place for all.”

Last year Facebook, Twitter, YouTube and Microsoft signed a code of conduct with the European Commission that requires them to delete hate speech within 24 hours of it being reported.
