I know that everyone's getting hit hard these days. I have another sob story though! Not sure if it's officially been sandboxed, but I've I've been had the same site nailed the same way within a month of it recovering from being nailed. Each time i was just about at 200 UV then bam, my home page is no longer indexed. Internal pages are still sitting at relatively the same spot but the home page is gone, unless I search for the exact domain. First time it was gone for 3 weeks. Hopefully this time is not longer. Funny thing is that I don't really have any "black hat" seo strategies going on for this domain. The only link exchange I've done is manual through linkspun (adult). Seriously only like 20 links. I have one other site that's never recovered from this same type hit, so hopefully I can come back, but damn!
