There was fun time when Ed Summers made a tool to monitor Wikipedia edits from some IPs pool realtime, and it turned into worldwide effort with Twitter bots monitoring many governments and big corporations, highlighting a lot of cringe edits and poor attempts to remove some info from Wikipedia. Many bots are still active, you can find source code and list of bots here https://github.com/edsu/anon
Also there is analysis of old edits (2002-2014) using IP ranges collected for bots https://jarib.github.io/anon-history/, source code: https://github.com/jarib/anon-history
