Amin ran the @Amreekiwitness Twitter account, which published pro-ISIS messages to a relatively small following, as well as directing followers how to make Bitcoin donations to the group. In one effort that proved particularly crucial to the prosecution's case, Amin arranged for an ISIS supporter to travel to Syria. All of Amin's efforts were conducted from within the United States, and there's no evidence that he ever took part in violent acts or intended to do so.

ISIS has been more active on social media than previous extremist groups, with a recent Brookings Institute study cataloging no less than 46,000 affiliated Twitter accounts. The State Department has made its own efforts at a counter-extremist Twitter presence, directly engaging with many radical accounts.
