EXTREMISMWhat Happened When Twitter and Other Social Media Platforms Cracked Down on Extremists

In a Q&A with ProPublica reporter A.C. Thompson, former intelligence officer and data scientist Welton Chang explains how conspiracy theorists and violent racists fled to smaller platforms. Once there, their remarks festered and spread.

Since Donald Trump’s election in 2016, an entire ecosystem of right-wing social media platforms has come into existence — from Gab (where the alleged Pittsburgh synagogue shooter posted hateful screeds) to Parler (a hot spot for insurrectionary activities in the run-up to Jan. 6) to the former president’s own Truth Social (which was frequented by a fan of his who was recently shot to death after attacking a Cincinnati FBI office). This new wave of apps and sites follows in the footsteps of 4chan and 8kun, older internet message boards that continue to attract a sizable audience of conspiracy theorists and violent racists.

Welton Chang knows this corner of the digital world well. A former Army intelligence officer and human rights activist, Chang runs Pyrra, a small tech startup dedicated to identifying and tracking the extremist ideas circulating in these spaces. Pyrra, which launched in early 2022 with $1.3 million in funding, monitors more than 20 alternative social media sites and online forums, scanning some 100 million messages per week.

Chang, a data scientist, says increased content moderation at major social media platforms — including the ouster of figures ranging from Trump to Alex Jones — has driven a sizable contingent of users to the spaces Pyrra tracks, which tend toward an absolutist view of free speech.

Can you tell me in simple terms what Pyrra does?
Pyrra is a threat intelligence company. We do three things: We collect content — publicly available information — from alternative social media sites. We use machine learning and advanced algorithms to detect violent threats, hate speech and disinformation that are popping up on these platforms. And then we display that information for our clients, either through reports or through a platform that we have.

We got our start in the human rights community. We were a project inside of Human Rights First [a U.S.-based advocacy group]. … We spun out of HRF as our own company in December 2021 and launched our platform earlier this year.
