[Techtalk] when to blackhole routes?

[Carla Schroder]

Under what circumstances does it make sense to blackhole routes? An obvious 
example is blocking spammers or other pests, like out-of-control web spiders. 
What about blocking RFC 1918 addresses entering or leaving your network with 
routing commands instead of iptables rules?

What else?
