`  :::Thanks for your responses. As you discovered, sort keys can be very tricky and complicated (such as WP:COP#Nobility). I believe that ListasBot has made several complete passes through Category:Biography articles without listas parameter, so most of the remaining ones are likely to need either a human's input or a bot with logic beyond what ListasBot does (adding listas from the article's DEFAULTSORT, , , etc.). I often work on it, but even with AWB's help, it's slow going, as I do manually inspect every edit, and often change them.  •  `
