I hope Google isn’t serious about their most recent indexing update. The proliferation of subdomain spam sites has accelerated, and not decelerated, as we all had hoped.
Take this one example, for keywords “poker sites”. The 1st page alone (out of 10 entries) yields 4 spam sites (all the same person, I’m sure):
espacioblog.com/myfiles/casino/poker-28.html
xoomer.alice.it/gambling777/poker-27.html
m4l.berlios.de/pub/Main/GamblinG/poker-16.html
galeon.hispavista.com/gambling777/poker-2.html
This is absolutely ludicrous, and is totally devaluing the net worth of Google.
