Welcome to the Q&A Forum

I personally wouldn't bother with Scrapebox - apart from the fact that it's synonymous with black-hat practices, you're far better served using tools like OSE and Majestic SEO. If you haven't tried Majestic I'd definitely recommend it, works really well in conjunction with OSE and GWT. Hope that helps!

The most recent forum post is dated Feb. 2012 and from there they go back several years to at least 2009. The way I found them was with a google "site:domain + my-company-name" search so I would think that means they were crawled by google Not using www was how I performed the search.
