I don't see how that could create a problem. The worst thing that could 
happen is that someone remains subscribed to a list when they should not.

Alternately, they could be unsubscribed because their MTA is returning the 
wrong error codes - but then that would give their postmaster a good reason 
to fix the error codes. In this case, they'd be unsubscribed as things 
stand anyway.
