- the harm done to its targets, either from personal harassment or from online spaces being experienced as hostile;
- the risk that those who encounter it may be radicalized by it, becoming more sympathetic and possibly even active; and
- the effect that it has on the values and culture of the online spaces in which it happens.
The internet has become a prime means of communication worldwide and this unprecedented global reach – combined with the difficulty in tracking communications – makes it an ideal tool for extremists to repackage old hatred, raise funds, and recruit members. As the internet has grown and changed, hate groups and movements have adapted, creating websites, forums and social network profiles, becoming active in spaces such as online games, and even creating parallel versions of services such as Twitter and Wikipedia.
Online hate can have an impact in three interconnected ways:
Since its earliest days, the internet has been hailed as a uniquely open marketplace of ideas, and it has become an essential means for people to access information and services. The downside of this is that, alongside its many valuable resources, the internet also offers a host of offensive materials – including hateful content – that attempt to inflame public opinion against certain groups and to turn people against one another.
It is not always easy to discern when hateful content on the internet crosses the line from being offensive to illegal. The line between hate speech and free speech is a thin one, and different countries have different levels of tolerance. The line is even thinner in digital environments where hateful comments posted lawfully in one country can be read in other countries where they may be deemed unlawful.
Information privacy is an important policy and social consideration.
There are two main strategies for addressing online hate and cultures of hatred in the classroom: teaching youth to recognize and deconstruct it, and empowering them to intervene by answering back to it.
The word surveillance comes from the French verb “surveiller”, which, when translated, means “to watch over”.  Sociologist and surveillance scholar David Lyon defines surveillance as “any collection and processing of personal data, whether identifiable or not, for the purposes of influencing or managing those whose data have been garnered”.  Increasingly, information gathering and surveillance technologies are becoming more and more common as part of everyday life and routines. 
Children and youth who use the Internet are highly attuned to surveillance practices.  Research conducted by MediaSmarts demonstrates that for young Canadians surveillance is part of everyday life. While youth once considered the Internet to be a private space where they and their peers could play, communicate, and experiment, these attitudes have largely disappeared: on the contrary, youth now regard the Internet as a completely monitored space.  This surveillance of youth is primarily conducted by parents, teachers/schools, and corporations.
Children and youth are a huge potential market for corporations.
There is a common misconception that youth are not concerned with privacy. On the contrary, though, there is significant evidence to suggest that privacy is a major concern among youth, particularly when it comes to their actions online.  As a result of this concern, young Canadians have developed a wide range of techniques to resist surveillance or negotiate their own privacy.
