Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 153 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

I saw a PPT posted by Jeff that showed a revision page which had the delete revision function, like this:

enter image description here

But I have never seen this functionality on SO's revision pages. I guess that's because I don't have the privilege.

My questions is: Who has the privilege to delete a revision?

Moderators don't - at least I'm not seeing it on the sites I moderate. – ChrisF Apr 6 '11 at 10:13
@Chris and other ♦, do you ever get requests to delete an older revision, like when people have accidentally posted credentials or privacy sensitive information? If so, then maybe a "hide" (soft-delete) of revisions for moderators might be nice? – Arjan Apr 6 '11 at 10:20
@Arjan - I've seen occasional flags to delete entire posts, but not specific revisions. – ChrisF Apr 6 '11 at 10:23
@Arjan It's pretty rare; they just get forwarded to devs. I doubt the system has support for "soft-deleting" a revision; it just removes it entirely – Michael Mrozek Apr 6 '11 at 10:24

Developers and certain other members of the Stack Exchange staff have the ability to delete revisions.

This is rarely used; two circumstances I can think of:

  1. User posts his or her password or SSN or {sekrit thing here} in a post. Don't laugh, it has happened. Revision has to be destroyed.

  2. A really silly set of edit wars going back and forth on a post for 10+ revisions -- I like to remove these because they bother me.

If you encounter a post containing sensitive information, edit it out (if possible) and then flag the post for moderator attention (a moderator will delete the post and get in touch with someone on the team to remove the revision before it is made visible again).

If you accidentally posted something containing sensitive data, edit it out, delete the post (if possible) and then contact us. Also, change your passwords immediately if that's what you inadvertently posted - we can whack revisions in our database, but we can't erase memories.

do deleted revisions influence CWification? – Tobias Kienzler Apr 6 '11 at 10:47
I did edit couple of posts recently that contained full details in connection string: database, user and password - should I flag them now so you can remove the revisions? – Shadow Wizard Apr 6 '11 at 11:05
Is it still the case that only Devs can delete revisions? Questions with proprietary or confidential information suggested emailing (before it was closed) but answers on What should I do if a user posts sensitive information as part of a question or answer? suggest flagging is sufficient. – Mark Booth Oct 22 '12 at 9:48
@mark I am not sure, you'd have to ask one of the SE community team. Good point to bring up, if this needs updating feel free to do so (or ping me and I will too). – Jeff Atwood Oct 22 '12 at 18:08
@Mark: flagging is actually preferable for truly sensitive information, simply because a moderator can quickly step in and delete the entire post until the revision is destroyed (which they'll contact us to handle). But you can also contact us, and we'll try to respond as quickly as possible. – Shog9 Oct 23 '12 at 0:26
Thanks @Shog9 I've updated my own answer to reflect this. – Mark Booth Oct 23 '12 at 9:11
Who come this option is not available to all? – dotNET Ninja Oct 29 '13 at 19:25
Bitcoin.SE occasionally gets people posting their private keys. In such a case it is certainly desirable to delete altogether (so that not even 10K users can see it), since anyone who gets the key can irrevocably steal the user's bitcoins. Unfortunately, in practice this probably happens almost immediately, so removal probably comes too late anyway. – Nate Eldredge Nov 26 '14 at 15:05
