So it's about two years since this thread began, but hey, better late than never, right?
So I'd been considering a brief return as a member of MET, and did so after this thread, in the hopes of locating the sets posted about.
They're gone. They don't exist.
You search for any of the titles? Nada.
Bourboulon? Two, recent results. None of the original stuff.
MET has totally scrubbed any of their original pre-2004 content, and pretty much all of their Bourboulon stuff. Such exist only now in the scatter remains of those who downloaded them a decade or so ago.
