I JUST got an email from The Cheerleaders. They are a group of hackers who have successfully shut down several jihadi websites. They just asked me to get the message out that with 30 UK people, they could "kill online extremism in the UK stone dead." Because of their track record, I believe they could.
If you live in the UK and you'd like to get involved, join one or both of these:
The British government has done very little to stop jihadi activities online. Jihadis have been relatively free to post propaganda, communicate strategies and coordinate plans online. With a little help from thirty British citizens, The Cheerleaders plan to put a stop to this. Join today.
