When Roku introduced private channels, it meant them as a way for developers to try their content before setting it loose in public. Well, that's not quite how it panned out: pirates have been using the channels to stream bootleg material. And Roku isn't putting up with that behavior any longer. TechCrunch, Cord Cutters News and TorrentFreak have learned that Roku now pops up a largely piracy-oriented warning whenever you create a private channel. It stresses that you should use a channel to stream "only legal content," and warns that Roku can pull channels with illegal material "without prior notice." It won't actively scan for piracy, but don't be shocked if your movie rip channel disappears in the blink of an eye.
