Twitter-owned video sharing application Vine has raised its age rating from 12+ to 17+ following controversy surrounding pornographic clips shared widely on the service.

Vine is one of the hottest new video-sharing applications, and its quick rise in just a few weeks led to the ouster of rival app Viddy’s CEO. But Vine has had a problem with users submitting easily searchable clips of porn, which was highlighted when someone at Vine accidentally placed a hardcore porn clip to the top of every user’s feed. Twitter responded to that incident by making Vine porn harder to find.

But it looks like that wasn’t enough to please Twitter (and perhaps Apple, who has blocked certain iOS apps for making risqué images and videos available). Now Vine has been bumped up to a 17+ age rating, likely to make sure parents will know questionable content can be found on the service. When you download or update the app, it now warns that the app contains “age-restricted material” and says you need to be 17 or over to download it.

On top of bumping up the age rating, the latest Vine update adds sharing to Twitter or Facebook after you post to Vine. The update also lets users report or block an abusive profile and fixes bugs.

Check out some recent Vine videos below to get a feel for the uses of the service besides porn:
