Prince's NPG Records has issued Twitter's Vine video app with a copyright complaint under the Digital Millennium Copyright Act, The Next Web reports.
The takedown request was sent on March 22nd by an unnamed label representative, who pointed to eight clips that contained "unauthorized recordings" and "unauthorized synchronizations." The offending videos seem to have been removed as the links listed at the end of the letter – which you can read at ChillingEffects.org, where Twitter posts every such copyright claim it receives – all lead to dead pages.
Twitter's copyright and DMCA policy, which is the same for Vine, allows the site to remove or restrict access to videos that contain copyrighted material. The site also attempts to contact account holders to explain the take down and how they might file a counter-notice.
A Twitter spokesperson said those were not the first takedown requests issued for content on Vine, though The Next Web found no other such complaints listed on Chilling Effects.
