Inside Terrorgram 

 

The Rise and Fall of an Online Hate Network

Over the past two decades, massive social networks have emerged as a powerful force for both good and evil. The ability to connect with like-minded strangers helped fuel uprisings like the Arab Spring and Iran’s pro-democracy movements. But it has also aided extremists, including brutal jihadist organizations like the Islamic State group and white supremacists around the world. 

In a joint project with FRONTLINE, we investigated how white supremacists from around the world turned a handful of accounts on Telegram into a community with hundreds of chats and channels focused on recruiting would-be terrorists, sharing grisly videos and spreading hateful content that promotes murder. They called it Terrorgram.

Last year, Telegram announced a slew of reforms designed to make the network safer. It promised to police illegal content on the platform and share the IP addresses and phone numbers of alleged lawbreakers with authorities.

Our investigation includes an upcoming documentary, “The Rise and Fall of Terrorgram,” which premieres tonight at 10 p.m. EDT/9 p.m. CDT on PBS stations (check local listings) and will be available to stream on YouTube, the PBS App and FRONTLINE’s website.

Since at least April 2021, the board has had evidence, including thousands of pages of patient files and medical reviews, that the popular Helena oncologist had hurt and potentially killed patients, ProPublica and Montana Free Press have learned. Weiner has denied the allegations against him, and a spokesperson for the Department of Labor and Industry, the board’s umbrella agency, did not answer a list of emailed questions.
