There's been a lot of PR recently about 'trust'. I know that Open Site Explorer and Majestic get a lot of their data from Yahoo and Bing as Google doesn't divulge such link data in the way that Yahoo and Bing do. I'm a big fan of getting the sleeves up and going deep into webmaster tools and cross referencing findings with advanced search paramaters in Google. The thing is, the third party tools show ALL links, Google et al only really care about the links they can trust, which are in webmaster tools, but not necessarily the ones at face value. Very cat and mouse im afraid.
