This is the story of one Canadian Facebook group, and the lesson it offers about what we're going to see on our social networks leading up to October's election. Canada's Yellow Vest protests are real. But not everything you see about them online is. It doesn't matter which side of the pipeline issue—or any other issue— you line up on, someone's willing to stoke that emotion for a profit.

There are real people behind online misinformation—what happens when you track one down? How do you spot a well-camouflaged bad actor hiding inside a sea of genuine political outrage? Why can't we stop calling one another bots and trolls? How has the term fake news become weaponized, and what can we do about it?
