The Thought Emporium just put out a video on Nebula (should be up on their YouTube channel soon) about this. This is a huge part of why every guide out there tells you to leave your phone at home when going to a protest, or at a minimum turn it off before you get there and only turn it on when you are at least a few blocks away. A burner phone is an option of course but that’s an additional expense and you need to plan for it.
