Sharing personal information online can lead to fraud, bullying, or worse. Both adults and kids are advised to never share their address, phone number, school address, or other identifying information. We have rules in place that forbid sharing last name, school name, passwords, email address, phone number, or street address. The good rule of thumb is to never share any information that could be used to identify you. When talking to people online, there’s always a chance that someone is misrepresenting themselves.
