Hi Holger, Suppose a group of people have recently met and exchanged email addresses, and are now engaged in time-sensitive communication. As an outsider, I can send an email to the group containing incorrect gossip for the group. This has a fair chance of disrupting inter-group communication, causing confusion and delay.
