Twitter's new Vine social video service, a "video Instagram" of sorts for sharing six second blasts of video content, has fallen afoul of Facebook, with users blocked from raiding their Facebook friends for new contacts.
Vine, which launched as a free iOS app yesterday, attempts to kickstart the sharing process by pulling in other users from Twitter and Facebook accounts; however, shortly after the app went live, those trying to import contacts from Facebook were faced with a message that the functionality had been disabled.
According to the original pop-up, Twitter's new app "is not authorized" to grab Facebook's data, leaving users facing manual adding of their friends on the site. That warning has since been changed to a more generic "An error occurred" dialog; there are also reports that Vine users have been unable to share their videos to their Facebook timeline.
A Facebook spokesperson told Mashable that the social network had no comment beyond the vague text of the error message. However, it's not the first time the company has yanked down the shutters to prevent rival social services from getting their teeth into Facebook data.
