So it's stupid. Or hostile. Certainly no more stupid (or hostile) than
sending out millions of spams, or being the source of thousands of
portscans/intrusion attempts, and refusing to take responsibility.

Bottom line: network policy is the responsibility of the network operator. =
If
he/she does something that causes bad repercussions (financially), he/she
will probably be job hunting. Otherwise, if it's not your network, you real=
ly
don't have much of a say about how it's run, do you?

(If it were otherwise, large sections of APNIC would have been cleaned up
long ago by those on the receiving end of portscans and spam.)
