analogy games are fun, but it boils down to this... If I know the real
source of an attack, I can stop it within minutes. I'm sure that my
customers appreciate that fact. Noone will ever completely stop attacks, the
point is to minimize their impact. that is my concern as a service provider.
also, from the victim's perspective, you have someone to hold accountable.

I think the spoofed source filtering is more a red-herring than anything
else. Its not the fix for anything related to this problem of attacks on
the internet. Spoofed or non, I can forward 1,000,000pps at your network and
it will die (most times).

This is like trying to fix a rotten decayed tooth with trident.
