I don't think black-hatters have anything to worry about. Spam techniques that this patent is chasing is totally different from black hat tactics. I've watched a local company here in my field climb to the #1 spot among 300 others vying for that same spot. They have been building a pyramid of sites for at least 4 years since I've had my eye on them. Their fully transparent public facing site is at the pinnacle. There's no way of picking them apart algorithmically so unfortunately they are untouchable unless someone reports them.
