Never give any personal information to anyone you meet online. That means first or last names, phone numbers (they can be used to track down you home), passwords, birth dates or years, or credit card information.
Never meet up with anyone you don't already know. Don't tell anyone your schedule; don't say where you'll be hanging out. No party announcements. People are often not who they say they are. It's true: 1 in 5 kids will be sexually solicited online.
Don't fill out any "fun" questionnaires that are forwarded to you, even if they're from your friends. Remember, you're in a world where everything can get forwarded. All those personal things about you could land in the hands of someone who could use them to harm you.
Make sure you know everyone on your buddy list. If you haven't met the people face-to-face, they may not be who they pretend to be. Also, Instant Messaging strangers is an invasion of their privacy.
You do not have to answer emails or IMs from people you don't know. As a matter of fact, you shouldn't. Who knows who they are? Even if they say they're "David's friend," David could be a lucky guess. "Kids" you meet in chat rooms may actually be creepy adults.
There's no such thing as "private" on the Internet. You may think so, but it's not true. People can find anything they want — and keep what you post — forever.
Be careful about posting pictures of yourself (if you must, don't post sexy ones or ones showing behavior you wouldn't want your mom, teacher, boss, or potential college advisor to see). Just because an older sibling has posted snaps on a site doesn't make it a smart or a safe idea. Pictures with identifiers like where you go to school can be shopping lists for online predators and other creeps.
Don't send pictures of other people. Forwarding an embarrassing picture of someone else is a form of bullying. How would you like it if someone did that to you?
Don't download content without your parents' permission. Many sites have spyware that will damage your computer. Other sites have really inappropriate content. Your parents can check your computer's URL history, so you can't hide where you've been.
Never share your password with anyone but your parents.
