Thanks, but I read that thread. Most of the posts on there were from people who did not believe it could happen. I am looking for software that can automatically spider all of the in-bound links and determine what links or domains are banned by Google. My client has had proof that negative SEO works. Their links shot up after the links were removed. Now they are going down and it's like trying to hit the weasel with a mallet trying to figure out who's doing it.
