( CNN ) -- Amid concerns over adult content popping up on its new Vine video app , Twitter appeared Tuesday to have restricted how users can share sexually explicit clips . As with Twitter , Vine users can create and search hashtags ( # CNN , # news , # tech , for instance ) to share posts with a wider audience or find lots of content about the same subject . By Tuesday morning , hashtags that had worked Monday -- including searches for the terms `` porn , '' `` nude , '' `` sex '' and `` naked '' -- were among those that delivered no results . That does n't mean that pornographic content has disappeared from the Vine app . But it 's no longer as easy to find , or share , huge caches of the stuff with a single click . Twitter did not immediately respond to a request for comment for this story . Rolled out last Thursday , Vine is a mobile app that lets users create six-second video clips and share them through the app , on Twitter , or both . While Vine has already been used to post some creative videos , like virtually any Web tool that allows user-created content it has also been used for the mass display of naughty bits . The issue came to the forefront over the weekend when an explicit video appeared under the prominently displayed `` Editor 's Picks '' section on the app 's main page . Twitter said the video appeared due to an employee 's error and it was removed . The porn issue was a public-relations stumble for Twitter and for what appears to be a quickly adopted app . Since its release , Vine has been among the most popular free apps in Apple 's app store . Currently , Vine is only available on Apple mobile devices . With its restrictions , Vine 's new model appears to more closely resemble the one used on Facebook-owned Instagram , the popular photo-sharing app . Salacious hashtags also deliver no results there . On Tuesday , there were still some workaround-style hashtags on Vine with which users were sharing adult videos . Presumably , Twitter might monitor and start deleting those as well .
Naughty hashtags are no longer working on Twitter 's Vine video app . Users had begun using the app 's 6-second clips to post porn . On Tuesday , # porn , # sex , # nude and # naked no longer delivered results .
