    Cyberbullying refers to bullying that takes place through interactive technology, particularly through the internet. It includes insults, embarrassment, and harassment. I think cyberbullying is dangerous because of some reasons.

    Firstly, cyberbullying is anonymous. People can be cyberbullied by a stranger or a close acquaintance without ever being able to tell who the culprit is. Bullies may feel empowered to say and do more destructive things than they would face-to-face when they are interacting with their victims screen-to-screen.

    Secondly, cyberbullying is permanent. It can be nearly impossible to rid the internet of offensive material that a cyberbully makes public; once a photo, rumor, or video has made it into a cyberspace, it may be there forever.

    Thirdly, cyberbullying is public. It can escalate what might once have been schoolyard disputes into smear campaigns accessible to the whole world. All it takes is for a "friend" to forward an email to friends who forward it further or to re-post or re-tweet a bullying for the bullying to "go viral" and reach a large audience.

    Lastly, cyberbullying is omnipresent. It follows you home. A student being bullied at school may find refuge in other spaces, but a victim of cyberbullying is connected to his or her tormentors whenever he or she is connected to a cell phone or computer-which for many teens is all the time.

    Based on those reasons above, it is obvious that cyberbullying is dangerous.
