Right, and my point is that you essentially can't. For my address the best you could do is narrow it down to ~30 or so homes that share the same first digit as my address.

They'll be able to narrow it down to 10-30 homes, but from there they can see who owns those homes, research those people on social media etc., and determine who their likely target is.
