**Reason**
Community Twitter [[ https://github.com/wikimedia/mediawiki-extensions-CommunityTwitter/commits/master | is unmaintained ]] except for the automated build and translatewiki.net updates. It is also [[ https://wikiapiary.com/wiki/Extension:Community_Twitter | just used on 2 wikis ]] whose versions are < 1.25 and therefore ain't no longer supported nor developed.
**To-Do list**
