I had a problem with one of my sites a while back that affected many of my pages but I won't go in to the problem in detail again here (visitor comments from 1 page were appearing on the wrong pages) but I fixed the problem and a few weeks later my top pages returned to where they were before.
Since the 14th Feb, I've been seeing these pages (with the wrong comments) appearing in the serps again if I search for them, even though they were all fixed ages ago. They returned to normal the 17th but have since returned and my pages have been buried again.
No idea what's going on, but I'm seeing strange results for a number of other keywords I search for daily also.
