I've never heard of identity theft. If anyone wants to claim this I'd want evidence, not hand waving.

But -

Like Ashley Madison? Medical records? Tax records. These have all had real life consequences for people. North Korean defectors had their details stolen the other day.

Like a email address to a site you comment on, so now it publically ties your comments to the real you?

Go on?

If your question is around identity theft which I think it really is, then I'd need to see proof, else the fear the NPCs have is actually what does the damage. (Also never heard of a domestic incident from a mass breach of addresses, I'd need proof to believe it, but it is enough to legitimately have to move house, so consequences)

(Passwords / unsalted/salted password hashes is of course the real killer, this has screwed a lot of people, but you've excluded this.)
