At minumum, a hurt can be put on networks that are irresponsible/innane by
effectively blackholeing them.

neighbor db.bad-networks.blah.someone.com remote-as blah-blah
neighbor db.bad-networks.blah.someone.com description DB of bad networks
neighbor db.bad-networks.blah.someone.com route-map blackhole in
neighbor db.bad-networks.blah.someone.com filter-list 2 out
!
route-map blackhole permit 10
set ip next-hop 127.0.0.1
!

Suddenlt being blackholed from those of use who don't wish to deal with
operators who won't/can't secure their network might actually get their
attention.  Much the same as denying the entire APNIC allocation in
.htaccess substantially reduces CC fraud on e-commerce sites.

I know.  It's akin to killing a fly with a sledge-hammer but sometimes
it's worth it.
