Broadly speaking, Terrorist Content and Activity is the use the internet to spread propaganda designed to radicalise vulnerable people, and distribute material designed to aid or abet terrorist attacks, however, there are a huge number of definitions of terrorism available as this is a highly contested term. One well-known definition is that contained in Title 22 of the United States Code, which states that terrorism is:

“…premeditated, politically-motivated violence perpetrated against non-combatant targets by sub-national groups or clandestine agents, usually intended to influence an audience.”

Violent radicalisation (including online) is a process whereby individuals, through their online interactions and exposure to various types of internet content, come to view violence as a legitimate method of solving social and political conflicts. Some of those violently radicalised via the internet may go on to commit acts of terrorism.
