Oh, this is about as black hat as you can get.
As ever with Black Hat SEO, it easier, but its a gamble. You can get software that registers a million blogs, spins a million versions of a few articles, interlinks and backlinks. I've never used Xrumer, but I've heard it mentioned enough times to know it must be doing something effective. Does it work? Yup. Are you always one review away from being kicked out of the SERPS? Yup. Is that a way to advertise a long term business, where branding, identity and customer retention is important? Definitely not.
Would I use it on one of my SEO clients? Nope. If I can get them to number 7 for a main keyphrase, using white hat techniques, we can keep invoicing them forever. If I spam, get them to number 1 for 9 months, and then they get kicked out, we can only invoice them for 9 months. For us agency SEO monkeys, it just doesn't make business sense. White hat SEO is an easier sell, anyway.
That said, if I were trying to make a fast buck by flogging an Ebook or something, I'd use blackhat spam, sure. I wouldn't structure a business around it, but I'd happily use it to make beer money.
