Findings that rest on exhibits naming this entity

  • INF-3.8: Wikipedia's policies base content on published, independent, reliable sources and presume a stand-alone article only for topics with significant coverage in independent reliable sources. Its perennial-sources page sorts sources into five statuses by community consensus. In the project's count of the page on 10 November 2026, the page had 497 rows: 472 carried a status icon (156 generally reliable, 112 no consensus, 148 generally unreliable and 56 deprecated) and 25 were blacklisted.
  • INF-3.9: A request for comment closed by volunteers on 8 February 2017 concluded that the Daily Mail is generally unreliable and its use as a reference generally prohibited, and the perennial-sources page's Daily Mail entry states that it was the first source to be deprecated. The page's definition of Deprecated in an archive capture of 17 January 2019 allows a deprecated source to be cited as a primary source when it is the topic of discussion, and the capture of 1 October 2026 does not carry that clause.
  • INF-3.10: Volunteer editors banned Wiki-PR on 25 October 2013, and counsel for the Wikimedia Foundation wrote to the firm on 19 November 2013 that undisclosed paid advocacy editing violates the Terms of Use. The Foundation amended the Terms of Use on 16 June 2014 to require paid editors to disclose their affiliation, and on 31 August 2015 it reported that volunteer editors had blocked 381 accounts and deleted 210 articles in the Orangemoody investigation of undisclosed paid advocacy.
  • INF-3.11: On 16 June 2021 the Arbitration Committee replaced community sanctions on COVID-19 articles with discretionary sanctions by an 8-1-1 motion that contains no findings of fact and no ruling on which sources count.
