Welcome to the Q&A Forum

That OSE crawl could just be a fluke. Perhaps retry the crawl next month. Regarding the 'parameters' in webmaster tools, did you tell Google to decide or did you choose ' Let Googlebot decide or did you choose "No: does not affect page content" option? Are there links to these search query pages from other websites? If not, then you might just need to give it time to realize that you set your parameters to ignore those URL variables. Another solution might be to add a noindex/nofollow to your search results page template. Scott O.

I'm more concerned about the number of domains rather than the number of links.  Google's usually pretty good at figuring out that those 14000 links are actually just one domain. If you've got a pattern of obviously manipulative linking then you may want to consider removing them.  But you could do yourself more harm than good in doing so though.  If the vast majority of your link profile is natural I'd ignore those self made links.  The only exception would be, perhaps, if these links all contained anchor text for which you were trying to rank.  Then there's a chance that a future Penguin refresh could get ahold of that.  It's a tough call.
