    (At the time, this was either the most or second-most upvoted
    post ever, and stayed that way for a long time.)

    Had the same idea yesterday (see my failed attempts at https://
    news.ycombinator.com/submitted?id=capableweb, unable to delete
    them after a few tries) but both the website + API were too slow
*   to update for me to be able to guess the right idea. When the
    website showed that one ID existed, there were already multiple
    ones created afterwards...

    Any clues to how you did this?

      I was basically just checking the latest ids (you can estimate
      it based on the /newest submissions and then increase until you
      hit the "No such item."-response.
[s]
      In my case I guess I was lucky that there was not much traffic.
      However I was on mobile when I started observing the ids but
      finally switched to PC as I felt on PC I can react much
      quicker.

      It's a PoC for HN related to this submission: https://
      news.ycombinator.com/item?id=33127285
[s]
      Basically I guessed the id of the submission (HN has a global
      counter for each comment or submission).

[s]
      That's... kinda of letdown. Was expecting a more intrigued
      approach but apparently HN is slow enough for guessing to work.

      I actually was first thinking about writing a small script to
      check if an ID is in use and then auto create a submission..
      however I first checked how often the ids actually change.. and
[s]   in the moment I checked it was about one new comment/submission
      every 30 seconds.

      I guess an timezone advantage .. when there is more traffic I
      guess the automation would win.

[s]   you can reference a YouTube video id in the video itself.
      that's much harder to do.

      Here's a short write up about doing this. https://varun.ch/
      video-id :)

[s]   It works because there are two requests associated with
      creating a YouTube video. First, the metadata is sent (file
      size, video title, etc.) and it returns a video ID. Then the
      actual video content is sent. I cancelled the upload request
      and replaced the video with a new one I rendered quickly.
