My site that was hit with Penguin droppings made it through all other updates with no problems. Loads of good original content, never sold or bought links, never even worried about it.
The only possible trigger I have found is a branded site hosted on affiliate domain that has several hundred thousand links back to the my site showing in WMT. These links were removed ten days ago, but still show in WMT.
After a 50% drop in traffic about 10% has come back. One site that pushed me down in rankings is like the poster child for things not to do, and yet it is getting better results.
Now its just a waiting game to see what happens. Income is still enough to pay the bills, but going to have to hold off on the Ferrari :) and settle for a bicycle.
