Stack Exchange deleted post user script

Stack Exchange Deleted Question Viewer

Screenshot

About

Stack Exchange Deleted Question Viewer is a user script which allows any users with at least 500 reputation to see most deleted posts, if they have a link to them. It will display the post's title, content, vote counts and comments. If the post has been edited at least once, it will also display the author and editor.

You can try this out with a deleted question and answer of mine on meta.stackoverflow.com, then consider taking a look at the Popular Deleted Questions list on meta.

Caveats

You will only be able to see answers when you use their permalink, or you voted on them answer before they were deleted. This will fail for locked questions, but should work for all others.

This script relies on certain bugs and design features that are likely to be changed at some point. I'll accommodate these changes if it's possible, but it may not be.

Stack Exchange Deleted Question Viewer was written me, Jeremy Banks. You can just leave feedback in the comments, but if you would like to email me my address is in my profile.

Code

Stack Exchange Deleted Question Viewer was written in CoffeeScript. The source file is available here.

Oh, and...

...if any Stack Exchange folks would prefer that this be deleted, I won't object.

Initial post IDs are taken from the URL.

For each known post ID:

  • /posts/ID/edit
    • Contains title, body source and tags of post.
    • If the post has been edited, it also contains the names, comments and IDs for each revision.
  • /posts/ID/comments
    • Contains the HTML text of the comments.
    • May provide the userid/name of the asker, if he has commented. Use this to get more info from real API.
  • /posts/ID/vote-counts
    • Contains the up/down vote counts for the post.
  • /posts/ID/votes (only use with the question)
    • Contains all votes/stars the user has cast on this question.
      • This may provide new post IDs to be searched.

Unused:

  • OP identification in comments
  • Tags at all (should be below post, at least)
    • Get counts via http://meta.stackoverflow.com/tags/TAGNAME/subscriber-info but with a huge throttle, because it's unimportant.
  • Infer rough version of title from URL, before full title is known.
  • Display real vote score, until it's clicked on.
  • Add flagging flaggy button stuff.

Do something in the side bar: maybe display revisions of the post?

Example revision-specific URL: http://meta.stackoverflow.com/posts/73412/edit/edc0a9c8-1ad0-44bf-94b9-608dba80b95d

/questions/QID/stub/AID#AID
