Me? Only one, and that was my totally-not-hacked shiny Mew.
I don't know about PNoob, though. He probably has had a million.

Edit: I've gotten two without looking, a Poochyena on Ruby (right before Petalburg, actually), and a Misdreavus on LeafGreen (Lost Cave). I remember that I caught the Poochyena in a Great Ball that my Zigzagoon's Pickup ability gave me, and that I told my friend there were orange Misdreavus's in Lost Cave, and she found one, too. I caught both of them in the fifth grade, five years ago, before I knew how rare Shinies are. So I restarted both files, sadly. Before I restarted them, they were both staple members of my two teams.
