A report by the Anti-Defamation League (ADL) reveals that a group of at least 30 Wikipedia editors has been introducing antisemitic and anti-Israel content onto the site. The report highlights a coordinated effort by the editors to edit pages related to the Israeli-Palestinian conflict, promoting bias and misleading information. The ADL calls for stronger measures to combat such content, including the creation of a reputable expert program and a committee to vet edits made to contentious topics.
