@crobb305, after reading your original post I went into my GWT and downloaded all the links with dates. What I found was quite similar to what you had in terms of the redirect spam to lead gen pages.
A number of these were .pl and .ru domains. I also took time to go through every single link individually, no matter how it looked on the surface. And here is an interesting thing I found.
Ever since I got listed in dmoz more than a year ago, I have seem many dmoz scrapper sites appear in my link profile. Normally I ignored them since you can't really do anything with them. But this time I went through all of these links and I found that more than half of these, what appear to be a scrapped page from the dmoz listing, actually redirect to a lead gen page. These pages are cloaked for the search engines.
Interestingly, some of these leadgen pages belong to quite reputable sites and if Google were to look into this practice, we will hear about many other brands getting slaps. These brands compete with me and I don't mind competing on fair terms but not like this.
I disavowed these links 2 days ago, with my comments, and will see what comes out of it. I suspect Google already knows about this practice and some of the negatives have rubbed off on my site so no reason not to disavow.
