The revolution might not be televised, but apparently it will be livestreamed, with so many posts from the revolutionaries about what they’re thinking and planning that the hard part is keeping track of it all.

The convoy protests centred on Ottawa have generated oceans of recordings: Twitter broadcasts, YouTube streams and shows, Facebook Lives and Rumbles, both on the scene and not, at all hours. Zello, a voice-chat app, has been an important organizing tool.

It can be messy even for participants. About 37 minutes into one stream recorded today, organizer BJ Dichter lamented the confusion online over who’s in charge—people announcing news conferences he’s not a part of, taking positions that the lead organizers don’t necessarily share.

“We’ve been dealing with, half our time, just getting people on board with messaging,” Dichter told YouTuber David Freiheit on his Viva Frei channel.

For security services and those who monitor extremism, it’s a vast resource—if they can separate the good stuff from the noise.

How to keep eyes and ears on it all: Telegram, the encrypted messaging service, is a popular medium for participants. “Just on the trucker-convoy stuff, I have almost 300 channels on Telegram I’m looking at,” said Marc-André Argentino, who studies the relationship between radicalism and technology at Concordia University in Montreal. “I’m getting thousands of messages [every] hour from the chats and the channels.”

In normal times, he has accounts organized by group and theme: one for monitoring conspiracy theorists, for instance, and others for neo-Nazis, for “accelerationists” who want to bring on race war, for general anti-government advocates, and so on.

He uses natural-language-processing tools to extract meaning from more video and audio than anybody could watch, social media analytics to spot terms that signal changes in attitudes and focus, and a certain Spidey sense developed from long exposure, he said.

Tricks of the trade: Avoiding repetition is key for people monitoring the material, Argentino said. “It’s trying to get the ones that more often than not [are] the originators of this content, over those that just amplify it.”

“I try to focus on chats over just channels because the broadcast channels, more often than not, are the propaganda that they want people to spread. What I find value in is how communities or the ecosystems of individuals are engaging with each other,” he said.

What to look for: Mere intensity of emotion isn’t enough, Argentino said—you can be a rabid sports fan without ever considering violence. Sharpening of tone and an increase in talk about violent acts, confrontation and civil war are danger signs.
