Under fire Twitter video-sharing app, Vine, has finally begun to filter out porn-related searches to prevent the rush of pornographic content to its network. Meanwhile, the micro-blogging Web site has apologized after 'human error' resulted in a pornographic video making it to the 'editor's pick' on its home screen.

Search for #porn, #sex or any other associated terms does not produce any results at this point in time, meaning the app now blocks such searches for pornographic content, The Verge reported. However, many related terms such as #pornvine and #nsfw are still allowed. "Users can also still tag Vines with pornographic hashtags, and other users can simply tap on those tags to pull up a feed of videos just like the previous search would have done," the report said.
It's an important move from the app makers to screen explicit content and to hide not safe for work (NSFW) material given the fact that its terms of service does not have a strict policy on porn content.

Meanwhile, Twitter has apologized for the mishap that resulted in a graphic clip of a sex act being shown as an editor's pick on the app's home screen.

"A human error resulted in a video with adult content becoming one of the videos in Editor's Picks, and upon realizing this mistake we removed the video immediately," a Twitter spokesperson said in a statement issued to Mashable. "We apologize to our users for the error."

As the Vine app is getting more into news headlines for all the wrong reasons, Apple swiftly and quietly removed the video-sharing app from its Featured Section on the App Store. Vine managed to appear on the Featured Section just the day after its launch on Thursday, swung to the top of Social in the App Store, and soon become number four free app overall.

However, the app disappeared from the Featured Section soon after the pornographic clip made it to the Editors' Picks section of the app. In a usual scenario, apps that are chosen for the Features Section remain there for at least a full week.
