Intentional exclusion of an individual by an aggressor who belongs to an online group (“friend list”), chat room, post, game or other password-protected environment.
Summary of Socio-Legal aspects
The word “bannare” can also be used to identify this particular behaviour. The aggressor does not “ban” any user that behaves against common conduct customs (netiquette) , but only a specific user, sometimes already a victim of bullying in “real life”. It is necessary to specify that the leadership of a person is determined not only by the number of contacts in real life, but also by the number of online “friends” and “followers”. In this perspective, the exclusion is a fully developed punishment, determining a severe reduction of friendly contacts, and causing a loss of popularity and “social power” .
The outcome, for the victim is a neverending series of abusive acts, in both the real world and the online world. Very rarely the relationship between the cyberbully and the victim may turn into a symmetrical one called flaming, if the victim can (with the usage of “anti-ban” software ), to re-enter online and insult, in turn, the cyberbully.
 Complex of customs that have to be respected by the users of a chatroom, a forum or another online service.
