A new way to attack Facebook on is to fraudulently report a news story as fake in the hope of reducing visibility either because someone will censor it or just disagree with it. Sometimes known as "brigading", a coordinated effort of troll to flag a content, reduce visibility. Facebook now sends stories that are reported as fake to third-party invoice controllers, and these targeted inaccurate reports can close the already crowded queues as invoice controllers are struggling to appreciate.
Therefore, Facebook gives users a credibility score ranging from 0 to 1 dependon reliability of their flag of false news, reports Washington Post. If they flag something like false news, but invoice controllers confirm it as true, it could hurt their score and reduce how powerful Facebook factors in the future flags. If users consistently report fake news that has actually proven to be fake, they improve their score and Facebook will rely on their future flagging more.
Facebook news feed product manager Tessa Lyons confirmed that the scoring system exists. There is currently no way to see your own or others' reliability score. And other signals are used to calculate the score too, although Facebook will not reveal them for fear of trolls played by the system.
This is not the only way Facebook ranks users. It assigns a changing affinity score to each of your friends who determines how often you see them in the news feed. This "friend ranking" score is essentially a distance distance target from you to someone else.
If you like lots of someone's posts, tag photos with them, search for them, view their profile, communicate with them, have many common friends, share the same groups and have similar biographical features as place and age, the score against them is lower and you will see more of them in feed. But they have a different score for you, depending on their behavior so you will not always see yourself in another profile if you do not see you in the feed if they do not reflect the interest.
Facebook Clear The need for this score highlights the difficulties with Facebook's fight against fake news. Between subjectivity and targeted trolling, there is a lot of noise coming in with the signal of what to remove. Anyone who says Facebook should easily have solved the fake news issues, probably underestimating the nuance required and the intelligent human opponents Facebook must defeat.
Facebook has a large selection of signals that it can use to calculate friend rankings or reliability scorers. The question is whether it can intelligently sort these signals to get coherent conclusions about what to show us and when to believe in us.
