Spam is a modern tragedy of the commons: as few as two hundred spammers pollute inboxes of hundreds of millions of Internet users, and will fairly soon account for half of all email volume. Fixing spam is simple if we permit ourselves to make slight changes to the Internet protocols. These protocols are supposed to be our servants, not our masters, but the technical community refuses to support a consensus to allow the tweaks that could cure not only spam, but worms too.* A simple modification to the SMTP protocol is now supported even by the author of the protocol herself.
