动态 | Scribd曾因澳本聪注册版权暂时撤掉Coindesk上传的比特币白皮书:据CoinDesk报道，澳本聪（Craig Wright）对原始比特币白皮书的版权注册已开始产生涟漪效应。5月28日，提供在互联网上发布可下载文件服务的Scribd通知CoinDesk已经撤下了CoinDesk上传的比特币白皮书副本。电子邮件显示，Scribd的BookID版权保护系统已经其禁止访问比特币白皮书，但这并不一定意味着发生了侵权行为。据悉，尽管澳本聪为白皮书注册了版权，但除非有人在法庭上对版权提出质疑，否则该版权注册毫无意义。然而由于像BookID这样的系统很可能会对美国版权数据库进行ping操作，因此该文件的副本将被公共服务处理。此后，Scribd法律运营经理Jason Bentley表示，该服务的团队已经审查了CoinDesk的回复，并确定Scribd的BookID版权保护系统可能错误地将该内容标识为侵权。Scribd已经恢复了该内容和相关指标。[2019/6/1]
