Unblockable Zuckerberg Story Is BS, Says Facebook Happens to users blocked 'large number of times' By Kate Seamons, Newser Staff Posted Aug 23, 2010 2:56 PM CDT 10 comments Comments Facebook CEO Mark Zuckerberg isn't unblockable! (AP Photo/Tony Avelar) (Newser) – This morning started out as Everybody Pile on Zuck Day, with the media (including your favorite site, Newser) reporting that Mark Zuckerberg is the only Facebook user who absolutely, positively cannot be blocked. Not so, according to a "Facebook spokesperson" (from the appropriately named "OutCast PR"). Writes said rep: "This error isn't specific to any one account. It's generated when a person has been blocked a certain large number of times." "In very rare instances, a viral campaign will develop instructing lots of people to all wrongly block the same person. The purpose of this system is to protect the experience for people targeted by these campaigns. We're constantly working to improve our systems and are taking a closer look at this one."
