Tangent: I've always wondered if forwarding spam (I don't use Gmail at all) to abuse@google.com works at all. Does marking spam from Gmail as spam count as reporting it? Or is Google one of those companies that either completely ignores spam complaints and/or makes spam reporting only work if you fill out a pain in the ass web abuse form?
