Everything you do online, whether it's posting pictures, commenting, or liking something, helps build a digital footprint. Leaving a mark of where you've been. This can be a really fun and positive thing. You can share things that reflect who you are, like your hobbies or interests, and you can become known online as being someone that acts like a good friend. But once something is shared online, it's hard to take back. Think carefully before posting or commenting, especially about anything that could hurt others or damage your reputation.
Imagine you're in a classroom and there's a whiteboard. You've got two marker pens. One is a whiteboard marker and the other is a permanent marker. With a whiteboard marker, you can write anything you want—fun drawings, notes, or doodles. But the great thing about the whiteboard marker is that you can erase it whenever you like. If you make a mistake, no problem. It's gone in a flash. Now think about the permanent marker. You can still write whatever you want, but if you write on the board with that pen, it stays there. You can't just wipe it away, even if you realize later that you made a mistake. It is stuck there for everyone to see. Awkward.
Your online reputation is a lot like using a permanent marker. What you post online—comments, pictures, or videos—can stay there forever. So it's important to think carefully before you post or comment, making sure it's something positive, reflecting the best version of who you are.
