So how is this being executed? Appears to have created a number of invalid categories. --Traveler100 (talk) 14:21, 20 September 2015 (UTC)Reply

@Traveler100: this is a system account run by the babel extension. If you see Special:UserRights/Babel_AutoCreate, "This user is a system user". Any issues should be reported on phabricator. --DannyS712 (talk) 08:57, 24 December 2019 (UTC)Reply
