[Description] Removing all or significant parts of a page's content without any reason, or replacing entire pages with nonsense. Sometimes referenced information or important verifiable references are deleted with no valid reason(s) given in the summary. However, significant content removals are usually not considered to be vandalism where the reason for the removal of the content is readily apparent by examination of the content itself, or where a non-frivolous explanation for the removal of apparently legitimate content is provided, linked to, or referenced in an edit summary. Blanking that could be legitimate includes blanking all or part of a biography of a living person. Wikipedia is especially concerned about providing accurate and unbiased information on the living; blanking may be an effort to remove inaccurate or biased material. Due to the possibility of unexplained good-faith content removal, {{uw-test1}} or {{uw-delete1}}, as appropriate, should be used as initial warnings for content removals without more. [Type]
