Online gender-based violence means when someone is being mean, hurtful, or harassing someone else on the internet because of their gender. This type of violence can happen in many ways, like sending mean comments or messages, posting embarrassing or mean pictures, or sharing private information without someone's permission.
It's like if someone was being mean to you on the playground because you're a boy or a girl. But instead of happening in person, it's happening online.
This kind of violence is very hurtful and can make people feel sad, scared, or embarrassed. It's important to remember that this kind of behavior is wrong, and people should always treat each other with kindness and respect both in person and online.
