I keep tripping over references (here's one) [google.com] regarding Panda being tasked with de-indexing of sites as well as ranking. Can this be true? Anyone has any idea what they're talking about?
This could be true but then Google is really lacking in the follow-up department! 6 months had passed between the break-in/fix and de-indexing. Still, I have sites that have been de-indexed yet never hacked into (located on a different server).
My gut feeling is either you still have some nasties left over from your last hack, or someone complained when it was hacked, followed by someone at Google deciding to block your sites.
