This account is part of the Babel extension and as such it is an automatic script and is not a bot in the usual sense. It automatically creates categories based on language levels added by users. The username can be configured through MediaWiki:Babel-autocreate-user and the content and names of the categories can be configured through MediaWiki:Babel-autocreate-text-main, MediaWiki:Babel-autocreate-text-levels and MediaWiki:Babel-category-override.
