Raunchy Vine videos prompt adult rating

SAN FRANCISCO (AFP) - The propensity for people to post porn evidently prompted Twitter on Wednesday to stamp an adult rating on an updated version of its Vine video-snippet sharing software.

Concerns were raised about two weeks ago, after adult content was bared briefly in an Editor's Picks section at Vine.

Twitter apologised for the mistake, blaming "human error" but providing little detail, and quickly removed the video.

Vine, a service that lets people share video snippets from iPhones or iPod touch devices, was launched in January by the globally popular one-to-many message sharing service.
