Firstly - anyone who reposts this will be someone who hasn&#x27;t seen it, therefore won&#x27;t have seen your comment.  Making this comment is therefore pointless.<p>Secondly, HN <i>has</i> got a repost filter.  Of late it&#x27;s been relaxed, deliberately, because there are downsides to being aggressive about preventing reposts.  Currently the system is under active development to improve the situation, but for now, simply pointing people to the previous discussions is enough.<p>Thirdly, while it&#x27;s a good thing that you have made the effort to create an account and comment, it would appear that you haven&#x27;t been here very long.  As such, direct criticism of the existing state of affairs might be the result of simply not understanding how things work, and what&#x27;s being done.  Have you sought out and read the previous discussions about duplication and the detection thereof?
