An online predator is someone who tries to hurt or take advantage of children or young adults using the internet. They might set up fake accounts on social media websites and pretend to be someone they're not, like a teenage boy or girl. They might also send emails, text messages, or posts to try to get kids to give out personal information like their phone number, address, or even meet up with them. It's important for parents and kids to stay aware of what's happening online, so they can spot and avoid online predators.
