Cyber-bullying usually occurs in the context of instant messenger  applications such as AIM, Skype or MSN Messenger. However it may take even great dimensions by becoming even more public, when it takes place in the context of public blogs or social networking sites such as MySpace, FaceBook, hi5, or even media hosting sites such as YouTube. Cellular phone tools such as SMS or photographic and video footage captured using a cellular phone may also be used as a means of cyber-bullying.

...is the preparation and psychological manipulation of a child with the intent of sexual exploitation.

• The first step of grooming is to gain the trust of a minor, with the groomer presenting his/her actions as beneficial for the minor.
• This may occur in the context of private communication via messenger programs.
• Other times it may occur in forums or Social Networking Sites. The individual who is initiating the grooming may have some sort of stature or position in the website which makes it easier to form a relationship with a minor.
• The goal of these interactions is to arrange a meeting with the minor, or to manipulate the minor so as to obtain pornography.
• Grooming can be the cause of psychological harm due to the psychomanipulation and seduction used by the groomer. It also creates a harmful model of minor-adult relationships. Grooming is a very serious offense that requires immediate attention. It may require direct cooperation with the police, motivating the child to report the offense and working with the
  victim’s family.

Signals of grooming may be:

• Showing interest or preference for a particular minor or expressing a willingness to meet in person.
• Sending pornographic images, videos or links to a minor.
• Leading a conversation towards sexual or age-inappropriate topics.
• Asking a minor to share personal or intimate images.
• Giving benefits or allowing a minor to get away with inappropriate behavior.
• Sharing problems or issues with a minor, which are not age appropriate.

...is the term used to describe an attempt to digitally break into someone's computer and access their files and personal information, manipulate their operating system, software or hardware, and generally to gain control of material on someone else's computer without their consent or knowledge.

• This can be quite distressing because it implies that someone may have accessed personal files, accounts and information.
• This may be the beginning of a variety of serious issues, with the perpetrator going on to perform a range of activities, such as fraud or publicly disseminating personal information.
• In other cases, the hacker's activities may cause the deletion of important files or damage to the computer, which may also cause significant distress.

...is the term used to describe an attempt by a party to extract another person's security passwords, personal information, banking details, user-names and other such sensitive information in order to commit fraud or extortion.

• Phishing emails are usually disguised as a legitimate enterprise or call for help, offering a large bulk of information which is supposed to convince the receiver that the subject of the email is true.
• For example, phishing emails may describe how the receiver has won the lottery in another country or has inherited a large amount of money from a distant relative. The emails are usually portrayed as coming from a national authority or legal representative, who asks for a down-payment to be made in order for the total sum of money to be transferred to the receiver's bank-account.
• Unsuspectingly, the receiver shares his/her banking details and personal information, only to find out that all the money in their bank-account has been withdrawn. The fact that the receiver gave his/her consent and sensitive details makes the matter very complicated from a legal standpoint.

...is the excessive use of the computer that interferes with daily life. Although this may seem ambiguous, there are cases where children and teens spend numerous hours on end playing computer games, chatting, or surfing the net while forgetting
their responsibilities or even to eat.

From a behavioral standpoint, it may be considered a compulsive behavior, clinically defined as a behavior which is performed not because it is enjoyable but because the individual feels that he or she has to.
 

...is a label for any sort of Internet content, whether verbal, visual or audio which may be illicit, dangerous, or age-inappropriate and yet publicly available.
