I've just read Spam: More or Less and it's the final point Joyce makes that rings true with me. As an individual I am certainly receiving less spam than I used to. But as an admin I know that the reason is because I've added Amavis and SpamAssassin to my network to filter out the spam before it reaches my mailbox. As an individual, that's great, as a network administrator, it is another item to manage and a little more work. As a responsible netizen it concerns me that the spam is still being sent and that it is deleted (albeit automatically) only after it's wasted CPU cycles, network bandwidth and in the process money before it reaches the machines where it is deleted where, in turn, it wastes my CPU cycles and bandwidth.
