Ewww.  p4pnet.net is part of a company Yahoo acquired that is still in the
process of being integrated.  :(

Personally, I'd just null-route the blocks--I'm sure it'll decrease the load
on the Internet as a whole while Yahoo works on trying to clean up their
acquisitions.  Of course, that's me speaking for myself, and not in any
way shape or form speaking for my employer.  ^_^;;

There are spam clueful people at Yahoo from the NANAE and anti-spam
communities--when stuff like this shows up in public forums, it does get
noticed and passed along.  I agree, it would be better if it could garner
the right level of attention without being called out in public forums like
this, though.
