Macebook?

I was talking to someone about shopping incidents when people were sprayed with Mace (pepper spray), and that made me wonder: Is there a website called Macebook where there are posted pictures of people who got Maced in public? I've looked up "Macebook" on Google, and there are apparently a bunch of them, but none of them that I saw listed this description as what their content was. Maybe it's a new one for Tumblr?
