It appears "people" are submitting the same link but with a different value after a hash (#) at the end of the url and the system doesn't recognize it's already been submitted. I've seen half a dozen "How I lost my $50,000 twitter username" submissions to thenextweb.com in the last 12 hours. Can we improve how this functions to prevent so many duplicates? Perhaps a ban on links to thenextweb.com??? I see before all these submissions one (that gained traction with HN comments) was to medium.com https://medium.com/p/24eb09e026dd https://medium.com/p/24eb09e026dd http://thenextweb.com/socialmedia/2014/01/29/lost-50000-twitter-username/#!tSomB http://thenextweb.com/socialmedia/2014/01/29/lost-50000-twit... http://thenextweb.com/socialmedia/2014/01/29/lost-50000-twitter-username/#!tSonU http://thenextweb.com/socialmedia/2014/01/29/lost-50000-twit... http://thenextweb.com/socialmedia/2014/01/29/lost-50000-twitter-username/#!tSoD9 http://thenextweb.com/socialmedia/2014/01/29/lost-50000-twit... http://thenextweb.com/socialmedia/2014/01/29/lost-50000-twitter-username/#!tSoJy http://thenextweb.com/socialmedia/2014/01/29/lost-50000-twit... http://thenextweb.com/socialmedia/2014/01/29/lost-50000-twitter-username/#!tSoSn http://thenextweb.com/socialmedia/2014/01/29/lost-50000-twit... http://thenextweb.com/socialmedia/2014/01/29/lost-50000-twitter-username/#!tSo71 http://thenextweb.com/socialmedia/2014/01/29/lost-50000-twit...
