Open source intelligence investigation of Gab

Gab is an American alt-tech microblogging and social networking service known for its far-right userbase. Gab's functionality is similar to that of Twitter. Users of Gab can publish posts, initiate private chats, join groups, livestream and buy products. Founded in 2016 and launched publicly in May 2017, Gab claims to promote free speech, individual liberty, the "free flow of information online", and Christian values. Widely described as a haven for neo-Nazis, racists, white supremacists, white nationalists, antisemites, the alt-right, supporters of Donald Trump, conservatives, right-libertarians, and believers in conspiracy theories such as QAnon, Gab has attracted users and groups who have been banned from other social media platforms and users seeking alternatives to mainstream social media platforms.

Researchers note that Gab has been "repeatedly linked to radicalization leading to real-world violent events". The site received extensive public scrutiny following the Pittsburgh synagogue shooting in October 2018. The perpetrator of the attack, Robert Gregory Bowers, had a history of making extreme, antisemitic postings on the platform, as well as messages indicating an immediate intent to cause harm before the shooting.
