Streaming music service Grooveshark’s legal woes have deepened, with news that Danish ISP 3 has been ordered to block its customers from accessing the service. The Danish Bailiff Court ordered the block after a case brought by entertainment industry body RettighedsAlliancen, which argued that Grooveshark had been “completely uncooperative” in negotiations with its members. “Grooveshark is an illegal site, which is really big and popular. But they have a business model that is based on trickery and fraud,” said RettighedsAlliance boss Maria Fredenslund after the blockage was announced. “Many users believe that when they use Grooveshark payment goes back to the artists and producers. So we think it was important to close off access so the legitimate sites have a chance to recover.” 3 says it is mulling its options, though, and may take an appeal to the Danish High Court.
