Hi, I'm doing a link audit.  My sites' keyword rankings and organic traffic have been sent to the Phantom Zone since the last Penguin Update. I've got 70+ and counting follow backlinks to my main domain and one of the my subdomains from http://www.secretsearchenginelabs.com/; should i disavow them? There's a load of links to many recognisable sites in there and my instinct's all out of whack with this decision. I think that these links were all manually added by a link building company on our behalf. It does look manipulated to me but i'd like a second opinion before I dump all of those links. Thanks Thanks
