Bullying is unwanted, aggressive behavior that is repeated over a short or long period of time. This can include verbal, physical, cyber or social bullying.
This form of intervention is where you respond directly to the aggressor. Make sure that you remember to: be confident, assertive, calm.
This form of intervention is where you distract either the harasser or the target with conversation unrelated to the harassment to diffuse and de-escalate the situation.
This form of intervention is where you bring in a 3rd party to help, possibly someone like a teacher, counselor, trusted adult, or principal.
Note: the 3rd party should not include peers
If you can’t intervene in the moment, you can check in with the person being harassed afterwards to see if you can do anything to support them.
"The Internet can be a wonderful place to learn, shop, play games, and talk to your friends. Unfortunately, there are also predators, identity thieves, and others online who may try to harm you. In order to be safe online, it's important for you and your kids to be aware of the dangers."
"Many kids are confident that they know how to be safe online. However, there are a few reasons kids are often more at risk. They may not always think about the consequences of their actions, which can cause them to share too much information about themselves. Kids also are sometimes specifically targeted by cyberbullies or predators."

Limiting the information about them online may also limit their risk of becoming a victim and may make it easier to identify the bully if they are victimized.
Avoid escalating the situation: Responding with hostility is likely to provoke a bully. Depending on the circumstances, consider ignoring the issue. Often, bullies thrive on the reaction of their victims. If you or your child receives unwanted email messages, consider changing your email address. The problem may stop. If you continue to get messages at the new account, you may have a strong case for legal action.
Document cyberbullying: Keep a record of any online activity (e.g., emails, web pages, social media posts), including relevant dates and times. Keep both an electronic version and a printed copy of each document.
Report cyberbullying to the appropriate authorities: If you are experiencing cyberbullying yourself – or if your child is being bullied or threatened online, report the activity to the local authorities. Your local police department or FBI branch are good starting points. There is a distinction between free speech and punishable offenses. Law enforcement officials and prosecutors can help sort out legal implications. It may also be appropriate to report it to school officials who may have separate policies for dealing with activity that involves students.
