I forward both Ebay and Paypal spoofs to spoof(a)ebay.com or spoof(a)paypal.com.
they then check them out and notify me if they are fake or real.
A couple of times I have forwarded regular traffic to the spoof notice and
got a return email telling me it is not a spoof.
I hope this helps them find the source.
