How sensitive is the phone's "I'm being tracked" algorithm? It doesn't go by tag owner but by Bluetooth Mac.
If I I buy 4 tags, register them all to me, overwrite the firmware on one so it rotates between 4 IDs, once every 15 minutes, then the phone won't see the tag as following it. Hell, you could glue 4 of them to transistors, a power supply, and a circuit to turn them on and off in rotation without modding the firmware.
It might! I don't know what's in Apple's closed source blob that implements the "am I being stalked" behavior and what parameters actually trigger it. Maybe you need to rotate between 60 tags, or 600.
