AOL could eliminate nearly 100 percent of its subscribers' spam with one easy change: it could simply shut off its internet gateway. Then, as of yore, the only email an AOL subscriber could receive would come from another AOL subscriber. If an AOL subscriber sent a spam to another AOL subscriber and AOL found out about it, they could terminate the spammer's account. Spam costs AOL millions, and represents a substantial disincentive for AOL customers to remain with the service, and yet AOL chooses to permit virtually anyone who can connect to the Internet, anywhere in the world, to send email to its customers, with any software at all. Email is a sloppy, complicated ecosystem. It has organisms of sufficient diversity and sheer number as to beggar the imagination: thousands of SMTP agents, millions of mail-servers, hundreds of millions of users. That richness and diversity lets all kinds of innovative stuff happen: if you go to nytimes.com and "send a story to a friend," the NYT can convincingly spoof your return address on the email it sends to your friend, so that it appears that the email originated on your computer. Also: a spammer can harvest your email and use it as a fake return address on the spam he sends to your friend. Sysadmins have server processes that send them mail to secret pager-addresses when something goes wrong, and GPLed mailing-list software gets used by spammers and people running high-volume mailing lists alike. You could stop spam by simplifying email: centralize functions like identity verification, limit the number of authorized mail agents and refuse service to unauthorized agents, even set up tollbooths where small sums of money are collected for every email, ensuring that sending ten million messages was too expensive to contemplate without a damned high expectation of return on investment. If you did all these things, you'd solve spam. By breaking email. Small server processes that mail a logfile to five sysadmins every hour just in case would be prohibitively expensive. Convincing the soviet that your bulk-mailer was only useful to legit mailing lists and not spammers could take months, and there's no guarantee that it would get their stamp of approval at all. With verified identity, the NYTimes couldn't impersonate you when it forwarded stories on your behalf -- and Chinese dissidents couldn't send out their samizdata via disposable gmail accounts. An email system that can be controlled is an email system without complexity. Complex ecosystems are influenced, not controlled. The Hollywood studios are conniving to create a global network of regulatory mandates over entertainment devices. Here they call it the Broadcast Flag; in Europe, Asia,
