Additionally, even if it were reasonable for ARIN to give legal advise
and for you to take it even if they gave it. There are so many "it
depends" on this one regrading issues like what country or jurisdiction,
the exact details of the situation in question, etc... The question
itself is almost meaningless.
That said, if an ISP is acting in "Good Faith" making reassignments
following reasonable business practices, and responding in "Good Faith"
to any complaints from third parties, it is difficult to conceive how an
ISP would become legally liable for the activities of their downstream
customers. However, I believe part of that "Good Faith" and reasonable
business practice is to provide and maintain public reassignment
information allowing third parties to directly contact the downstream
customer. Part of that "Good Faith" is to maintain and update that
information, if you have reason to believe it is not correct.
If that information is not publicly available, it is private, then I
believe "Good Faith" would require you to act as an agent of the
downstream customer and at the very least to accept and convey any legal
paperwork to the downstream customer. Probably more than that minimum
for a practical perspective, but from a legal perspective it would be
absolutely necessary to convey any legal paperwork.
