facebot
A robot in disguise who thinks it’s a human. It only talks to Facebook, not to you.
Facebot: "I just got a notification that you’re having a bad day. Let me tell you how bad my day is."
Facebot writes on its wall: "My friend just got a promotion. I got a notification. That’s good enough for me."
You: "Why did you add me?" Facebot: "Because I got a notification."
