THE poisonous work of Birmingham cyber-hacker Junaid Hussain is being continued by fellow jihadis pumping out more than 90,000 Twitter messages a day. Now experts from the US-based Counter Extremism Project (CEP) say his ‘cyber warfare’ efforts have been taken on by new recruits vying to replace him as chief propagandist for IS. CEP is now calling on Governments around the world to take stronger measures to prevent IS’s online activities.
