Digital citizenship refers to appropriate and responsible behavior regarding technology use. It involves thinking carefully before posting online by considering whether the content is true, helpful, inspiring, necessary, and kind. Users should avoid sharing personal information, stealing content, lying about their age, or visiting unfamiliar websites. They should keep social media profiles private, use strong passwords, treat others with respect both online and off, and act as upstanders by reporting signs of bullying. Examples of good digital citizenship include disabling location services and citing sources, while bad examples involve posting identifying personal information, plagiarizing content, or sharing work issues on social media.
