PayPerPost Puzzle

The folks at the PayPerPost blog have started an Internet Puzzle game in which the pieces are apparently scattered all over the internet, with a nice cash prize to the winner.

I consider myself a preety savvy internet user, and I have no idea how to go about this. Start visiting PPP users and just look around, perhaps?

Intriguingly, the blog says that the last puzzle was solved by some programmers who managed to cheat programmatically. I can't imagine how this could be done!
