According to a statement made on Wednesday, a group of Jewish students and an anti-hate speech organisation have filed a lawsuit against Twitter (TWTR.MX) in Germany, claiming the firm failed to take down anti-Semitic information.
HateAid and the European Union of Jewish Students criticised what they called a lack of moderation with regard to material that can encourage hatred.
Six posts that the groups claimed to be anti-Semitic were the subject of the complaint, which was lodged in a Berlin court but not removed despite being reported. The groups said that in one instance, the deletion of a post that denied the Holocaust was expressly rejected.
Denying the Holocaust is illegal in Germany.
HateAid and the EUJS stated in a statement that they were investigating whether Twitter users had the legal authority to enforce the service’s terms and regulations, which include not tolerating threats and abusive behaviour.
Requests for comment from Twitter did not immediately receive a response.
