On spam-l it was reported that there presently is a valid address of spoof
(for the purpose of sending abuse complaints about spoof paypal
websites) at paypal.com. Since ebay now owns paypal, I suspect you can
use that address to report spoof sites and emails for either service and
that the human at the other end has enough clue to realize that they should
act on all such spoofs reported to that address.

one can easily imagine that their abuse@ alias was receiving so much spam
that it was too costly to read it all and fish out the valid complaints.
(this is a ~recent spammer tactic, clogging the metadata paths to make it
harder for network owners to discuss spammer activities.)
