You know who really annoys you? That Facebook CEO Mark Zuckerberg. You hated that shrimp in The Social Network. So you know what you're gonna do? You're gonna block him on Facebook. That's right. You'll show him. And while you're at it, you'll block his wife.
Oh wait... you can't block Mark Zuckerberg or Priscilla Chan!
This isn't that new. Users haven't been able to block Zuckerberg since January, but Priscilla Chan's profile is a recent addition to the cannot-block club.
