Wikipedia editors have decided to declare one of the leading human rights organizations in the United States, the Anti-Defamation League, as an “unreliable source” whose data cannot be relied upon when it comes to the Israeli-Palestinian conflict, a report published Wednesday night reveals.

The Jewish organization is one of the most prominent and well-known in terms of protecting and supporting the rights of Jewish citizens in particular and minorities in general in the U.S., and it constantly fights to ensure the security of American Jews and to stop the rising antisemitism in the country.

Wikipedia editors’ decision to categorize the ADL as “a source that is generally unreliable” means that from now on, it will not be possible to quote data or statements from the ADL in articles posted on Wikipedia, except in exceptional cases. Thus, the organization joins a list alongside state-owned media outlets in Russia, Fox‘s political coverage and Amazon reviews, all defined as “unreliable sources” on Wikipedia.

The ADL strongly denounced the decision. In a written statement, the group said the decision was the result of a “campaign to delegitimize the ADL” and that editors opposing the ban “provided point-by-point refutations, grounded in factual citations, to every claim made, but apparently, facts no longer matter.”
