Users of Vine finally have the option to share their videos after they are posted after the newly-released short video app from Twitter got an update that also adds an age rating, following issues with pornographic content. Version 1.0.5 of the app, issued today and first spotted by The Verge, brings the new sharing options and also sees the 6-second video app becoming the latest in a series of top services to get a 17+ age rating. Vine’s advisory was previously for users aged 12 and upwards, and the change follows the discovery of widespread pornographic content on the service. Vine follows Tumblr and 500px in adding the age rating. The 500px app was actually initially removed from the App Store all together over the concerns about content. It was reinstated after adding the option to report photos.
