RedWarn MAT Users

SQL

-- =======================================================================
-- This query will check Wikipedia for all edits tagged with "RedWarn",
-- and find all users of RedWarn from these changes. This also includes
-- users who have used RedWarn previously but have since uninstalled
-- RedWarn. Since RedWarn is commonly used in conjunction with Twinkle,
-- this also counts all Twinkle edits by the users. This will also check
-- if the user is currently blocked or not.
-- =======================================================================
-- NOTES:
-- 
--  * Twinkle only started using the "twinkle" tag on September 2020.
--  * This includes users who have uninstalled RedWarn.
--  * This does not distinguish selfblocks.
--  * This checks for expanded RedWarn features (given if 30/500 passes.)

-- Improved by RW developer Chlod, forked from AntiCompositeNumber's original
