I think there's something bigger going on. At work we have non-Google accounts and it's gotten worse there as well. Like all of a sudden about 3 or 4 months ago, I just started getting bunches of very very obvious spam that wasn't caught by our previously pretty good filters. (Subjects like "Meet Russian Brides" and From fields of "Foo Print Advertisement", etc.) I wonder if someone has figured out how to game the current system or something?
