Protect your friends' and acquaintances' privacy, too. Don't give out their personal information except how to contact them, and never give any web site your list of email or phone contacts. Don't tell a company such as Facebook anything about your friends that they might not wish to publish in a newspaper. Better yet, don't be used by Facebook at all. Reject communication systems that require users to give their real names, even if you are going to give yours, since they pressure other people to surrender their privacy.
