After being flooded with pornographic images, the iPhone app for Twitter's video sharing service Vine has changed its rating from 12+ to 17+.
This means users will have to confirm they are 17 years old or over before using the app.
Originally, Vine was rated 12+, but it decided to change the rating after adult images started showing up on the service, some even in the "Editors' Picks" category.
Photo sharing app 500px as well as Tumblr were also forced to change the rating of their apps due to adult content.
The new rating has been introduced in the new version of Vine (1.0.5), which also brings the ability to share vines to Twitter or Facebook after posting, report or block a profile and various bug fixes.
