@ superclown2 - what did you do to the affected sites ?
I changed the position of affiliate links so that they were read at the end of the page by the spiders. "Poor" quality pages were taken out. More links were asked for and received to badly affected pages, which promptly fell further. Pages were re-written wholesale, and new pages added to make the whole site more relevant to the targeted search terms. At no stage did any page actually rise in the SERPs for the targetted terms and the sites as a whole continue to receive fewer and fewer clicks.
I've pretty well abandoned the pandalised sites now, to sink or swim as Google wills.
