I'm quite concerned that phone numbers I don't own or addresses I no longer live at have legal "owners" and their friends/sublets who could decide to impersonate me with accounts that still have these old details, and its kind of hard to separate that from my new details having been the illegitimate hack. I think most people wouldn't risk that unless they are pretty messed up and an average legal system to deal with that unless it is pretty messed up. A past residence in a mediocre city in the US provides all the crack heads needed for such a torturous comedy.
