Each year people, send mail to as many mailing lists as they can asking to be put on them instead of the request list. Several times a year, someone configures a mailer to cause a huge loop that causes many megabytes of mail messages to be sent to many people on many different systems. At least once year, I see a piece of code written under the assumption that the network is a quiet high-speed high-relaibility medium -- the code retransmits quickly and has very short timeouts. Lastly, we have several systems that take a list of hosts and broadcast messages to them to update databases. This is in the similiar flavor of grapevine. It is not unlikely that some company could set up a system and want a broadcast facility similiar to the one that started up this discussion. At this point, it is no longer a security problem but a feature. If I had concrete improvements that I could implement, I would act on them. Maybe the system will change to charge for mail and to charge for network access and usage. People would then be more responsive to their utilization of those resources. -Rudy
