> Big tech companies have also met U.S. government officials earlier this year to discuss how to stop ISIS from recruiting terrorists on social media. The Obama administration had asked the companies to develop techniques to detect radicalization, and block pro-ISIS messages, photos and videos.

If they're blocked from Twitter, they'll just move on to some less easily accessible platform.
