While the paper is well written and Johnson's case is clearly made, her solution seems simplistic. She leaves unanswered the question of what to do with those who do not follow the rules. Also, to establish norms, users must agree on the rules. This is difficult to accomplish offline, let alone online. Respecting the privacy and property rights of others requires agreement on what those rights are.
Spammers claim the right to send commercial email to anyone, which many recipients reject.
While Johnson offers some initial norms, she gives little help on the more difficult task of getting a diverse global online community to agree on these or any norms. The Digital Library is published by the Association for Computing Machinery.
