Twitter has updated the terms of service of its Vine video-sharing social network to prohibit explicit sexual content. Vine added that "a very small percentage" of videos posted on the network "are not a good fit for our community."

"We don't have a problem with explicit sexual content on the Internet ?? we just prefer not to be the source of it," Vine said in a blog post Thursday.

Vine said it would allow depictions of nudity or partial nudity that are primarily documentary, educational or artistic in nature.

Vine will rely on users' feedback to enforce the ban on sexually explicit videos. Users can report videos by tapping the button with three dots below the post and selecting "Report this post".
