Gmail Spam Failure

53 new messages in my Inbox this morning, and only 6 of them are not spam.  This is ridiculous.  Here's the body of one of them (with a bit of editing):

babes amazing big boobs get a good tit f**king
blonde teen sucking and f**king in the kitchen

How can Google not think this is spam?

I want a whitelist feature, and I want the ability to plug in my own spam filter.  I'm going to have to start using POP to download my mail from gmail and read it with something else, something that can actually filter this stuff.
