Which just verifies what the last AC said.

At the very least it's an voluntary initiative to work at cutting off terrorist usage of Twitter and potentially other communication systems that are being used to distribute terrorist related propaganda. I agree that many recruits probably don't come from Twitter, but it's still a distribution network for their own propaganda. Terrorists always win when people are afraid, an audience is still a pretty important factor for them. In addition to fueling the the hatred of those who support them, it still expands their reach of mindshare in the world, to the point of inspiring other nut jobs that this is a serious war that's worth dying for. It's not going to make them go away if we work together to reduce the abuse of social communication systems, but we don't need to sit idle and just allow them to use our systems to advertise their "war".
