YouTube is the most popular online destination to watch and share videos.
However, hidden beneath all those cat and dogs videos, carpool karaokes and prank videos, is a mammoth reservoir of pornographic content.
YouTube has strict guidelines prohibiting publishing porn and any pirated content. But as per a report by TorrentFreak, many uploaders are exploiting a loophole to avoid detection.
"By uploading a video without publicly publishing it, adult sites are able to host it on Google's servers and embed direct links to it on their own sites," says a Mirror.com report.
The report further adds that the videos are not directly listed on YouTube but are saved on GoogleVideo.com domain server.
These videos also bypass a system called ContentID which allows copyright owners to report pirated content to YouTube administrators.
"There is a big loophole on YouTube. Copyright infringers take advantage of a private-video-share setting. They upload and store videos, and freely use them on third party websites to earn profits," explained Dreamroom, a California-based porn producer that spoke to TorrentFreak.
