Here is my story that is quite different then what you would find regarding Penguin 3.0 in general. So I have a bunch of money making sites, that were through each of the Panda and penguin update (in 2.5 years) without any hiccups only to get manually penalized by Google in January (when competition reported me after being unsuccessful to surpass my sites). So I left those sites with absolute no link building to them. Just 2-3 days back I was thinking to send a reconsideration request (I did send a good disavow file to Google 25 days back). So yesterday I came to BHW forum after a few days, saw the Penguin 3.0 shit, go to serpbook and dang my sites are back into business - from page 1 to page 5 now.
