It may have taken years of campaigning and complaints but Twitter has finally banned pornographic images on its Vine app.
The Californian-based firm, which bought the video sharing app in 2012, announced the changes on Thursday and the new rules come into effect immediately.
Within days of the app's official launch in January 2013, sexually explicit and pornographic clips began to appear and Twitter has been heavily criticised for not enforcing this ban sooner.
The new rules do come with a series of caveats, however. For example, nudity will be allowed in documentary style clips, if it forms part of an artwork or sculpture, or if it is used for educational purposes.
Breastfeeding clips are also allowed.
Elsewhere, sexually suggestive content is also allowed, such as suggestive dancing, as long as the people in the clip are clothed - although close-ups of aroused genitals underneath clothing are banned.
The new rules forbid any video of sex acts, sex toys used during sex acts, and sexually graphic animations.
'For more than 99 percent of our users, this doesn?t really change anything, ' explained a Vine spokesman.
