I want to know how someone can threat another online and what is the meaning of cyber bullying? ?
In addition to Tamsyn Mathew's excellent answer, I would add that Cyber Bullying is not necessarily an issue in which someone "threatens" another. It is about generating a circumstance in which one or more person's "torment" another person.
Some unevolved persons, (otherwise known as "social primitives") obtain a sensation of power
by dominating another. Almost any unkind thing said or written, in a repetitious manner, equates to Cyber Bullying. It does not have to involve a threat of harm. The verbal abuse is itself the harm,
going so far as to suggest that another person should commit suicide etc.
Oddly, some people enjoy the feeling of pain and torment that they can create in another.
Cyber bullying is a form of bullying except instead of it being face to face abuse, the bullying happens on a mobile phone or a computer and the abuse is usually on a social media site like Facebook or Twitter etc. If all my friends at school send me messages to my mobile phone making bad jokes about me because of something I did then I could feel like I was being cyber bullied. If I write something on Facebook and a whole lot of people decide to they don't like me or want to make bad jokes about me so then they all comment on what I have written in a malicious or mean way so that they can embarrass me on the internet as other people on the internet can see what they/I have written. Cyber bullying could also be that somebody steals your identity (your profile on facebook) and posts pictures of you or others which you don't want to put on the internet because the photos are private and not something you want to share with the public. They could also write bad things pretending to be you if they manage to steal your profile and although it is fake it is embarrassing because people laugh at you. Its the same as bullying except the people who are bullying and the people who see the bullying are witnessing everything on the internet on a computer or mobile phone screen.
Cyberbullying is the use of cell phones, instant messaging, e-mail, chat rooms or social networking sites such as Facebook and Twitter to harass, threaten or intimidate someone. Cyberbullying is often done by children, who have increasingly early access to these technologies. The problem is compounded by the fact that a bully can hide behind an electronic veil, disguising his or her true identity. This secrecy makes it difficult to trace the source and encourages bullies to behave more aggressively than they might face-to-face.
Cyberbullying can include such acts as making threats, sending provocative insults or racial, attempting to infect the victim's computer with a virus, and flooding an e-mail inbox with messages. If you are a victim, you can deal with cyberbullying to some extent by limiting computer connection time, not responding to threatening or defamatory messages, and never opening e-mail messages from sources you do not recognize or from known sources of unwanted communications. More active measures include blacklisting or whitelisting e-mail accounts, changing e-mail addresses, changing ISPs, changing cell phone accounts, and attempting to trace the source.
Because the use of mobile and online communications has grown so rapidly and the crime is relatively new, many jurisdictions are deliberating over cyberbullying laws. However, the crime is covered by existing laws against personal threats and harassment. In some cases, it may be advisable to inform the local police department or consult an attorney. It is not recommended that you retaliate in kind because such behavior can lead to heightened attacks, or even civil actions or criminal charges against you.
