I don't know if there is a way to filter that site out using the free or paid versions.
As the SEObook review notes at the end...
In running a couple of comparisons against Open Site Explorer and Majestic SEO it was clear that Spyglass has a decent database but needs more filtering options (sub-domains mainly). It's not as robust as OSE or Majestic yet, but it's to be expected. I still found a variety of unique links from its database that I did not see on other tools across the board.
Most of the tools err by reporting too much data on large sites. If you can't filter out the ROS links, you don't have much of a shot (in a limited report) of seeing unique referring domains, which I feel is the data that's most valuable.
Blekko's data, btw, is free and it has some nice display options, but its index is extremely limited. One big limitation... Blekko doesn't include what it considers to be "spam" in its index, which makes it difficult to analyze sites that may have spammy backlinks, something that as an SEO you'd want to be able to see and at least diagnose, if not try to correct.
As far as finding domains to ask for backlinks, good arguments can be made that search information coupled with imagination is more valuable than competitive backlink information.
