Dropbox clarifies its policy on reviewing shared files for DMCA issues
For years now, Internet users have gotten used to the risk of having files and content they share through various online services be subject to takedown requests based on the Digital Millennium Copyright Act (DMCA) and/or content-matching algorithms. But users have also gotten used to using services like Dropbox as their own private, cloud-based file storage and sharing systems, facilitating direct person-to-person file transfer without having to worry about such issues.
This weekend, though, a small corner of the Internet exploded with concern that Dropbox was going too far, actually scanning users' private and directly peer-shared files for potential copyright issues. What's actually going on is a little more complicated than that, but shows that sharing a file on Dropbox isn't always the same as sharing that file directly from your hard drive over something like e-mail or instant messenger.
