Vine, the Twitter-owned short video sharing app, has updated its user age rating to 17+ after a major increase in porn sharing on the service. The change first made appearance in the 1.0.5 update and forces users to confirm that they are 17 years or older.

The app also added frequent/intense sexual content or nudity, infrequent drugs, alcohol, tobacco, horror/fear themes, profanity/crude humor and realistic violence, to its list of user warnings. Last month, the service began censoring searches in an attempt to weed out the pornographic material from even showing up.

These changes come on the heels of a porn video being featured on Vine as an "Editor's Pick" which got the app pulled from the Apple App Store's featured section. Despite the controversy, Vine has proven to be massively popular on iOS with many analyst relating the app to the likes of "Instagram, but for videos."
