I bet some RF absorbing material or something that reflects RF at weird angles would probably break it. Or an active RF transmitter.

Build an electronic warfare device that makes it look like hundreds of people are inside, all pointing guns outwards.

Make all walls a Faraday cage / concrete. If you can’t get cell or radio reception inside, you probably aren’t leaking anything either.

anything metal in the way. I'm sure the image would be a lot less clear if the wall had metal studs instead of wood.

Carry something metallic, so the neural network no longer classifies your reflection as human?
