This tool intersects the contributions of two or more users on a given WMF project, showing the pages edited by all of them.
It can help in discovering sockpuppets.
Update:On 2016-04-05 I updated the tool to support the intersection of the contributions ofmultiple users.
Unfortunately, to handle this in a reasonable way, I had tochange the format of the URL parameters.
The old URL format ( "user1" and "user2" ) is still supported, but eventually this will be removed.
This means that existing links to the tool referring to a specific couple of users will be broken.
- You can provide between 2 and 8 users. Empty fields will be ignored.
- The pages can be filtered by namespace.
- Please note that intersecting edits of users with huge contribution histories may take some time.
