Adult video websites appear to be exploiting a YouTube loophole to host explicit material on the platform. News site TorrentFreak found some sites had uploaded videos that did not show up on YouTube, but could be viewed on third-party websites. The exploit allows a website to host its video library for free, using Google's server space and bandwidth. YouTube told the BBC its policies "prohibit sexually explicit content like pornography". Videos can be uploaded to YouTube under a "private" setting that prevents them from appearing publicly on the website or in search results. This setting also disables the embed function that usually lets videos be posted on other websites. However, TorrentFreak reported that some websites had found a way to play secretly uploaded videos on their own external services, by streaming the raw data from googlevideo.
