You can resubmit a link after a year, I think? In any event, there's no way to block resubmissions programatically: the site owner could just change the name of the file.

Or people could append random query parameters, HN would have no way of detecting that http://example.com/?foo http://example.com/?foo, http://example.com/?bar http://example.com/?bar and http://example.com/?baz http://example.com/?baz points to the same article. No need to change anything on the webpage.

The page content's hash or any other blueprint (an arbitrary regex match) could be checked against for resubmissions. For convenience, if resubmission should be detected, the original post could be topped on the frontpage nevertheless, because old material may as well be worth revisiting for several reasons -- I for one had missed this article before, and enjoyed it reading greatly now.

  page content hash Change one byte. regex match Now we get into ship-of-theseus arguments. What counts as the "same" article? 99 percent? 51 percent? What if you resubmit a blog post that's picked up 150 more comments since it was last posted? How would HN tell the comments apart from the article text? What if someone submits a blog post that heavily quotes another article that's been submitted, in the process of rebutting it, and ends up being a 80% match? What if you include the full text of moby dick, in a display:none <div>? What if the page loads the text of the article with javascript? Would the HN submissionbot have to render CSS and javascript?

    > Change one byte. Most resubmissions are submitted by people other than their authors, who are typically not in a position to change any bytes of the content. In the present case, speaking as the last person to submit this one (more than two years ago), I don't see that there's any harm in it at all. If this is still interesting two years since it was last discussed on HN -- which clearly it is -- then good for the submitter, who has provided the HN audience with something interesting to read.

      The slightest spec of dynamic content makes this approach brittle at best, author or not.

        You probably meant "speck", not "spec".
