spam by routing it through the computers of their Internet
service providers, rather than sending it directly from individual
machines, the experts said.

The result is that "blacklists" of known spamming computers --
which other network operators rely upon to block mail from those
machines -- are no longer effective. To block spam coming directly
from an ISP's computers, all mail from that ISP would be have to
be blocked, which would cripple electronic communication.
