In http://bbs.boingboing.net there is a little game that where we communicate only by changing the text of the thread title/subject. While edits are archived in vanilla Discourse, certain agitators had this data removed from public access.
Now, the originator of the thread still receives notifications, but some hoops must be jumped-through.
I grabbed the list by going to my notifications, opening page-inspector, selecting the element that held the notifications, copied the innerHTML and save that to a file.
This file is then processed via node.js - see eat.js
Caveats - title-edits by the thread originator are not visible, since the originator receives no notifications regarding own edits.
There is another view-edit feature on the thread-page itself, but AFAICT it requires clicking through each edit.
Discourse also has an API that I haven't looked at.
