Hey John -
I'm really not convinced there was any negative seo in the sense that the term is being meant of late. I believe our past seo company built blog network links without consulting us. The foreign porn site links are more of a mystery. I'm reluctant to submit a reinclusion request in case they manually make rankings worse, what do you think about that idea? Our site has not tanked, but all major KWs have dropped 5-10 spots. A couple havent budged since getting the letter.
