Twitter’s six-second video-sharing app Vine launched with a bit of a porn problem. Vine scurried around and quickly turned the porn problem into a much lesser porn problem by banning many porn-related searches and hiding NSFW material behind warning screens.

Today, they launched an update to the app that carries a new 17+ rating in the App Store. Short of banning nudity, Vine has done pretty much all they can to make pornography as inaccessible to the wrong kind of eyes as they can.

Anyway, Jon Stewart finally got around to addressing the porn issue. Watch the whole thing for some bonus jabs at Facebook.
