The Merc sent a photographer out there? Like a real newspaper?

Oh, it's a stock photo of some random person on some random river.

That's helpful.

Doxing isn't specifically related to activists/activism. It's just a thing. That's like attributing shouting to only activists. Or cheeseburgers.

Doxxing is absolutely one of the most vile practices of "internet activism." Ask Zoe Quinn, for a start.
