There is actually an active "BJ" group in the Phoenix Metro area. It was about a year ago when I noticed they were slapping up custom graffiti stickers on Central Avenue (Midtown).

Then later, I saw their handiwork in person: they would take an angle-grinder and obliterate the QR Code from those rental e-Scooters, slap on a BJ sticker or three, and then leave them where they found them. This would render the scooters as e-waste, un-rentable and blocking the sidewalks.

I would not be surprised if they are quietly influencing groups which are agitating against AI Data Centers. But the BJ I have seen is a chaotic group of direct urban sabotage.
