The great thing about FB is that these spammers have to sign up and be traceable within FB in order to spam their wares. It's easy for FB to track them down.
If FB becomes the place where people communicate, and they can offer a spam-free environment to do so, that could be one of FB's greatest achievements. The walled-garden model is really going to take off with this sort of press.
