WikiTeam is connected to the ArchiveTeam, but we use our own software: https://www.archiveteam.org/index.php?title=WikiTeam https://github.com/WikiTeam/wikiteam
The reason is that wikis, and specifically MediaWiki, provide open formats and protocols which help export and import, unlike the general web which can only be archived by some generic-purpose HTML format (WARC).
