Just browsing through my spam folder and noticed a spam with the following URL:
http://yahoo.com.collectiza.com-munged/vp9
(without the -munged of course)
Looks like they might think that putting yahoo.com on the front will fool a simple parser ? :) Have we been "noticed" already or am I just being paranoid ;)
That particular spam didn't match on that test, but did match on another different URL in the same message...
