We focused on email spam because that's been our area of expertise for the past few years. Some of these programs are well represented in SEO spam as well - with affiliate programs like these, they don't much care how you bring them the customer traffic as long as it arrives. We haven't, however, looked into the programs that are exclusively advertised via SEO but it's definitely on our list. Most of our methodology will carry over, we just have to straighten out how to create some sort of canonical feed of SEO'd pharma links. I'd also like to personally thank you for your employer's generosity in supporting this research :).
