// [[Wikipedia:Requested Articles]] Cleanup Tool

// When the user EDITS a page starting with [[Wikipedia:Requested articles/Business and economics/Companies]], this script adds a "Remove Bullets With Too Few References" button that the user can click.

// Clicking it will delete all bullets with 1 or 0 URL's, because these entries will not pass [[WP:GNG]].

// Certain things will safelist the bullet, including clerk endorsement, a link to a draft, and some other conditions.

// The [[WP:RA]] company lists are massive. So far, this tool has helped delete 150 companies that did not follow our submission instructions that require providing enough sources.
