Rule by Law
Every user on the network has an equal right to protection.
Justice is due to all, without regard to wealth or status.
It is useless to have rules made by users of their own choice, if the terms of service are so long that no one will read them; or so confusing that no one understands; or if they are so weak that no one will enforce them.
It is better for one hundred spammers to escape than for one innocent user to get banned.
