Vine [3], that six-second video share bought by Twitter last year [4], has brought in an NC-17 rating after last week's...porn-y situation [5]. You might recall that was when an X-rated video was accidentally made an editor's picks. And so, as The Verge [6] notes, the video-sharing [7] site's 1.0.5 update for its app now contains the little blue box asking users to confirm that they are over 17--a slo-mo video replay, if you like, of what Tumblr [8] did last week [9].

The update also allows users to share their video on social media after they have posted it on Vine, with Twitter- and Facebook-share buttons. This is a fairly fast work-around to Facebook's recent blocking of third-party access to its users' data [10], the very same move it had busted the month before [11] with Instagram, meaning users of the photo-sharing service couldn't post photos directly into their Twitter feed.
