Cyber bulling is a terrible thing. It is where a person online targets another person and calls them mean names or other hurtful things. It also is where someone makes you believe that it is one person, but it really is someone different. Cyber bulling is considered where someone is on a electric device or not in person and saying bad things about you.
Some ways you can try to prevent is by not going on the internet. You can tell someone right away and then they can help you with it. Also you don't want to say anything back so it doesn't get any worse then it is. If you are getting cyber bullied tell someone because it might push you over the breaking point and you might do something you will regret. So get help/ tell someone right away.
