Its not even just providers.  If it were, it'd be relatively easy to

Do what I did and give people a way to test connectivity from both
affected and unaffected space and setup a 'hall of shame' page listing
the IPs/networks that are behind broken filters.
Can someone identify the *benefits* of using bogon lists for unallocated
space? It appears that it only hurts connectivity, but does not help in
any significant way to enhance security.

It might be a way to proactively keep your part of the network 'cleaner'
than the other parts... 'managed' properly and 'updated' regularly (when
changes dictate an update is required) it might even be seemless to your
userbase.

The devil here is, as always, in the details. Once you move beyond some
number of devices or acls or 'parts', making changes on a wide scale and
keeping things up to date becomes more difficult. Change management and
the number of hands in the pot seem to make these things much more
challenging.


Possibly, whoever are the vendors of software that recommends this
practice (and authors of security handbooks) should be show the error of
their ways?

if they did they'd lose part of their punch :( And lose some of their
readerbase... and who'd call you to complain? :)
