The joke is on you guys

I really like how the April Fools joke is going. You see, M00t ACTUALLY connected the boards to Facebook. That's the actual joke.
...so it's kind of funny to see people who think they're so clever, go "Aww, that's such a lame joke. M00t would never link us to Facebook.". Just choose Show Source on the "Post Successful" page, and you'll find the Facebook page where your post ends up.

I don't get it because I don't use facebook. I have no friends ;_;
