Contribution Surveyor

Contribution Surveyor is a tool by User:Dcoetzee that is used by en:Wikipedia:Contributor copyright investigations on the English Wikipedia, to analyze the contributions of users with a history of copyright violations. It goes through all of a user's contributions, determines the number of bytes added or removed in each contribution, and then presents a list of articles the user has contributed to, ranked by the size of the maximum contribution. This is useful for identifying contributions that are most likely to be copyright violations.

I'm no longer making major changes to this project and consider it mature and completed, but this may change in the future.
