Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 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

This duplicated question was closed because being a duplicate, however, the dup box is missing (there are manually added links1 by a Mod though).

Why is the duplicate box missing in this old post?

1 related post that shows the community reaction of manually adding dup links in posts.

Probably because that question was closed as a duplicate before the box got automatically added. – Cody Gray May 13 '12 at 5:12
@TheEstablishment that is one of my theories too (but I want to remove all doubt), anyway, I am sure in a future others will have this same question, so it is worth to create this post – ajax333221 May 13 '12 at 5:41
BTW, I made a SEDE query to find posts like this. Suggested edits to add the links in (usually found in the comments) have been met with mixed approval/rejection votes, so I stopped doing it. – a cat May 13 '12 at 17:36

If you look a little closer, you'll see it was also closed by one user, who isn't (and wasn't then) a moderator. And that I'd edited in those links a day prior to it being closed. Things were pretty different in early January of '09...

As The Establishment theorizes, there was no automated system for adding those links back then. We edited them in by hand (usually before the question was closed, so that folks could find them quickly) and if it was re-opened later, edited them back out.

Oh, and I wasn't a mod then. Strictly-speaking, I'm still not.

did you get a notification somehow or it was pure coincidence?, I am impressed how you found this question so quickly :) – ajax333221 May 13 '12 at 15:58
It popped up in the list of meta questions when I checked it before bed ;-) – Shog9 May 13 '12 at 17:29

The first "insert duplicate link" revision made by Community bot was first introduced in May 20th 2009 in this question, you can see it logged here. (Oh, and quite buggy at first :))

The feature change log we got here on Meta only starts at October that year, but the feature was announced on the blog:

We tried to look at the existing way the community was dealing with duplicate questions and streamline it into as few steps as possible.

...So when the question you saw was closed that feature simply didn't exist yet like Cody said in a comment.

If you want more evidence that May 20th was the date, you can find the announcement here: – Shog9 May 13 '12 at 7:02
@Shog9 nice, was looking for such thing. Want to add it to your answer and I'll delete my own? – Shadow Wizard May 13 '12 at 7:04
Naw, this is fine - I was headed to bed last night, and too lazy to edit it in. – Shog9 May 13 '12 at 17:28
