- don't say something online that you wouldn't say in person
- if someone you know sends you an email addressed only to you, at least read all of the text that they wrote themselves (i.e. if they forwarded or quoted someone else or included a link to a webpage, that doesn't fall under this rule)
- if someone is anonymous or pseudonymous and you know something about their real identity, don't reveal the information about their real identity to others without the consent of the person being identified
