Ask HN: Are submissions allowed more than once on Hacker News? Yesterday I came across an interesting wikipedia page and thought of sharing the site on HN. It was "Timeline of the far future". Someone commented and noted that the same link had been posted multiple times before (link: https://news.ycombinator.com/item?id=8029426) In the past, I had been unable to submit links that were already submitted at one point. Does anyone know if multiple submissions are allowed? Is this a bug? |
If a story has had significant attention on HN in the last year or so, we kill reposts as dupes. When posting, you should first check HN Search: https://hn.algolia.com/?q=timeline+of+the+far+future#!/story.... As you can see, it appeared in the last year. I think 23 points counts as significant, especially since there was a huge thread the year before.
Coincidentally, we updated the HN FAQ last night to answer this question.
Finally, please re-read the HN guidelines. Questions like this aren't supposed to be posted to HN itself. You should email hn@ycombinator.com.
Just gave the HN guidelines a thorough (and much needed) read.
Music to my ears!
Lately though, this has seemed like less of a problem, so I wonder if something was adjusted in the HN ranking sort.
The problem is that canonization is very difficult, it's very easy to get false positives, and each site needs a slightly different canonization rules. So the current method is to use manual moderation.
And when the server restarts, it forgets the old url's for a while, so there are some possible repetitions.
And in a very few times, resubmissions are good.
Most of the resubmissions are accidental, good faith resubmissions. Someone just copy the url and the browser / link / site internationalization was different.
I think there are not official rules, but the unofficial algorithm is:
* When a submission was recently discussed, and it's resubmited the moderators may kill it.
* If the discussion was a long time ago, the resubmission may be left alive.
* If none of the previous submissions get many comments / points, the resubmission may be left alive.
* If there is an intentional systematic resubmission, the moderators may hellban the user and put the domain in the autokill list and other nasty things.
For example read: http://blog.wolfram.com/ All the blog can be resumed as "You can do a lot of calculations and nice graphics with Mathematica" But many of the individual post have interesting information (and nice graphics) and got a lot of points https://hn.algolia.com/?q=wolfram.com#!/story/forever/0/blog...
Each of the submissions to that wiki article have slightly different link structures. For example, one has a trailing "/" and one does not.
Link.com/mysubmission
Link.com/mysubmission/#
Link.com/mysubmission/##
Link.com/mysubmission/###
Link.com/mysubmission/####
I'm not sure if it pisses people off but that's the technique I've used before. Resubmit at different times of day. It's tough to get your submission exposure because different crowds are on at different times of day. So really good articles can be ignored simply because they were submitted at the wrong time or wrong day and no one was there to upvote it. That's what I've always hated about Digg/Reddit/HN. You have to submit stories at some magical time.
