John I disagree - the ISP should only be contacted by ARIN after an
attempt is made to contact the ISP by the complaintant and the ISP
has proven nonresponsive.

No this isn't an exact analogy because the privacy laws basically
prevent other parents from contacting the parent of the kid without his
homework (since the teachers are prohibited from discussing the
kid with other parents) so the school has to be the one to call the
bad parent.
