サイト削除
マルチサイトからサイト削除
If you delete the site with plugins active that had created database tables, then those tables are not cleaned out when you delete a site. They will remain as artifact tables. What I recommend is to take note of the blog id of the site you are deleting. For example the 8th blog in the mu install will have tables named wp_8_ prefix. This should help in identifying artifacts later.
