I'm struggling to figure out OP's context (not sure why they're not just saying it) but one thing I can come up with is restraining orders.
It doesn't seem too outrageous to me that the use case of 'have been in a neighbourhood for a while and already have enemies' is just outside of the scope of the program, though. It has far more utility for people who have just moved to a new town and have no contacts at all.
