I don't have SEOQuake.

My only method is searching "Posted by" + "keyword" and that's a keyword that I get from the 5000 most popular adwords keywords, ones I figure would be spammed a lot.
I suspect, Micallef, you have your own very clever ways of doing it that you keep to yourself. I respect that, I simply feel grateful for your kind answers, they are truly pearls of wisdom for a noob like myself. That goes for kendra too.
What I am finding about these "bad neighbourhoods" is that, even the top ranked, most squeaky-clean looking websites have their foundations in the most dirty, spam filled neighbourhoods. I came from a white hat background, paying indians thousands of dollars for something I could have done in an hour myself with scrapebox or magic article submitter, thinking this was the only way. But the truth is, to get on top you have to be either a massive authority and genuinely popular, e.g. youtube, which is rare, or you 'spam' your way there and completely fake your popularity in the dirtiest neighbourhoods imaginable. The thing is, these spammers who are on page 1 have linked directly to their money site, and because I have watched their sites for a couple of years now, I know their position at the top has not changed. They have not been G slapped so I guess they are lucky. I personally would not spam directly to the money site. Oh well, I guess I still got a lot to learn.
