In a blog post on Thursday, Vine—the Twitter-owned, six-second looping video service—announced that it had updated its terms of use to prohibit sexually explicit content from appearing on the service. Practically since launch, Vine has been trying to figure out how to handle adult content. Regardless, Apple forced the company to change the age limit on its iOS app to 17 or older due to the potential for sexual content. Twitter—Vine’s parent company—allows users to upload photos and has similar safeguards for explicit content in place, but does not have an age gate on its app.
