"We have seen the video but have been unable to replicate the experience it shows," a Facebook representative told CNET in a statement. The company also once again detailed how its display-filtering technology, which surfaces news to user feeds, has built-in safeguards to keep potential spam out (emphasis mine):
"Newsfeed is an automated system that is designed to deliver the most relevant content to you and your friends. The technology evaluates hundreds of factors, including your relationship to the poster, the type of content, the click-through rate (where appropriate), and people hiding similar posts from their feed. In real time, it decides what to display to you and what to filter for both Top News and Most Recent. It also includes systems that attempt to identify and block spam. Links have a history of the most abuse and are given the most scrutiny. As a result of all of these factors, a given link may be shown or filtered to people differently at different times."
