Facebook is lying to your friends about what you like in order to sell them things they don't need
Facebook Is Recycling Your Likes To Promote Stories You've Never Seen To All Your Friends - Forbes
Condon continues, “most individuals have no idea this is happening. Any post made by Facebook on your behalf is completely invisible to you, and only shows up in your friends’ & family’s news feed.” In many cases, these are innocuous. In some cases, your Like implies an interest in everything posted by the brand liked, but, obviously, not always. Sometimes your mom thinks you’re promoting rudeness!
“This goes beyond just advertising on a user’s behalf,” Condon writes. “My friends & family might think I like inappropriate content, or information I don’t agree with—it can damage relationships. In fact, I’m only familiar with this issue because a friend asked if I liked “[rude thing goes here!].” What else has Facebook posted on my behalf that I don’t agree with? What has Facebook posted on your behalf that you don’t agree with?”
You can say that Facebook is clearly labeling the content as “related,” but to the untrained eye of the average Facebook user, these posts look like any other. And unlike Facebook Ads that you can opt out of sharing the liking of with friends, or the sponsored stories that you can’t opt out of but at least are mentioned in Facebook’s Help Center, Related Posts are a completely undocumented feature.
It’s hard not to see this as intentionally manipulative and misleading on Facebook’s part. It has already made a preliminary $20 million settlement over its use of Sponsored Stories, but that’s not the worst of it. A story from ReadWrite by Bernard Meisler documents a boatload of cases where friends had supposedly liked brands that the writer couldn’t imagine them ever liking. Some of these friends were no longer even alive!
