Twitter pushed out a new update to its Vine iOS app today that adds sharing features, as well as a new 17+ age rating.

Version 1.0.5 adds the ability to share Vine videos to Twitter and Facebook after they’re posted, and a new feature to report or block users (not just specific clips), plus other bug fixes. What’s even more noteworthy, however, is the age rating. That’s clearly a response to the news that the micro-vid service is awash with pornographic material. Prior to this revelation, Vine had been rated 12 and up.

As a gesture, it serves to acknowledge the existence of adult-oriented material on the service, and it probably appeases Apple and its App Store censors standards committee. But as a useful tool, the new rating’s not going to make one bit of difference. Surely even kids 16 and younger will be able to click a button to bypass a warning pop-up. The report or block users feature will be handier. At least people can flag offending users or bypass material from these accounts at their discretion.

To access it, go to “Profile” and hit the new “…” button in the top right.
