There doesn't seem to be a plausible way to fade inconspicuously from well-attended magic spying without mental tampering that might not even work. But perhaps Bella can make it register the way it would if she died, or lost the characteristics on which she's being monitored, instead of as though she jammed the detector. If the hypothetical stalker comes and checks on her in person she will have a chance to identify them: they will be looking at her. Hard.

A hex goes.
