- as more people's mailboxes are protected by anti-spam filters,
- and as those filters get more accurate,
- fewer spam messages get delivered,
- so fewer products get bought from spam,
- so less commission goes to spammers,
- so the economic incentive to spam dries up.
What should be done? Anti-spam software should delete messages that are clearly spam. When modern spam filters assess a message, they do so using a battery of tests and criteria. This process usually produces an aggregate score. Some spam messages score so high that they're clearly spam. There's practically zero chance that this might be a legitimate message. Anti-spam software should only present grey-area messages to the user in the quarantine.
