I think that Cisco's Autosecure feature is part of the
problem here:

http://www.cisco.com/en/US/products/sw/iosswrel/ps5187/products_feature_guide09186a008017d101.html

While it says that bogon filters change, and provides
a URL to check it, what percentage of folks who would
use a feature like "autosecure" would ever update
their filters?  

sigh.
