A man who authorities say wanted to start a race war stayed on the social network Gab for days after he was arrested for allegedly inciting violence on it, according to a Hatewatch review. Gab, which is known for hosting white supremacist content, boasted on Twitter on June 17 it suspended Joshua John Leff for violating site rules. But police apprehended Leff on June 14, meaning his account stayed active three days later, Hatewatch determined. Furthermore, Gab CEO Andrew Torba contacted Leff’s account in April 2019, according to an archive of a post reviewed by Hatewatch. The two men conversed about a technical glitch that was impacting the site at that time. Police arrested Leff, 40, on June 14. The Florida Department of Law Enforcement alleges Leff engaged in written threats to kill and possessed a firearm as a convicted felon. Authorities say Leff went by the alias Paul Atreides and the handle @DarkLord79 on Gab. At least one picture shows a man using the Paul Astrides alias brandishing a firearm, according to Hatewatch’s review of his account. (…) The post and hundreds of others written by Leff across many months remained up on Gab.com until at least June 17, 2019, Hatewatch determined in a review of Leff’s Gab account. The posts included language and images appearing to call for the killing of Jews and LGBTQ people.Hatewatch reached out to Gab to inquire about Leff’s account but did not immediately receive a reply.The Anti-Defamation League (ADL), a rights group that monitors white supremacists, posted a comment to Twitter about Leff on June 17, noting that Gab was “the same social media website used by the white supremacist behind the #antiSemitic Tree of Life synagogue shooting.”Robert Bowers, a white nationalist who posted to Gab under the handle @OneDingo, awaits trial in the Tree of Life case. Bowers has been charged with 44 federal charges in connection with the deaths of 11 Jews at that Pittsburgh synagogue on the morning of Oct. 27, 2018, making Gab a national news story.
