@chalkywhite - you are definitely not alone.
I have wondered how Google treats links like these, where a single site will either scrape part of your page for a very specific keyword, and/or use this scrape for the anchor text in the 'Resources' section of links at the bottom of the page, often with many/every other site in your niche or for this particular keyword or query.
I'm interested to hear what happens to your site's rankings after Google's had a chance to digest all of those links being removed.
I've been reluctant to go after these links because for so long the conventional wisdom and Google party line was that they ignored or didn't factor these links into your rankings, and more recently - reluctant to go after them because I'd lose such a large # of links overnight - like you did.
What about the hundreds of whois, 'site profile', 'site info', and 'site valuation' spam sites that form a baseline of spam/unsolicited links that almost any new site will get - how does Google treat these? While most of them are only one link each, should we try to get these links removed too?
