HN has a feature that uses the canonical address in the webpage. Is your page configured correctly?

Looking at the source:

  <link rel="canonical" href="http://hackflow.com/blog/2023/03/26/ban-1-plus-n-in-django">

Don't repost it again (for now). Try fixing the canonical link, and send an email to the mods hn@ycombinator.com with a short explanation and a link to this post https://news.ycombinator.com/item?id=35313565 to save them a few minutes searching. They may fix it using admin magic or ask you to repost again once the problem is fixed.
