one of the things I cover a lot in the security trainings I do for movement spaces is something I don't hear a lot about in the privacy space atm - and that's active counter surveillance
you start small with things like data poisoning, intentional signal creation, etc. that looks like mistagging geos on social media, clipping your favorite BLE tracking device to your indoor/outdoor cat that you also borrow for your own keys, scripts/macros that will randomly click-through ads, etc
another idea I had was just using those magnetic bumper stickers to confuse things like Flock cameras in combination with IR/reflective bumper covers since those services tend to profile cars based on a lot more than just the plate - wish this was something I could test but alas, an insider with an ethical backbone has yet to leak their source code
