It's probably a total waste of time, but any spam that gets through my filters and has what appears to be a valid reply address and from a US origin, I forward to spam@uce.gov and CC the forward to the spam-monkey. It usually stops those in particular, but they are replaced by ten more.
Before forwarding to spam@uce.gov, be sure you open up any options that reveal the full email header.
Now, I have no indication that this is worth the effort, but it only takes an extra half second on the way to the delete button.
