Penguin has only been refreshed once. I feel it might be easier to escape than Panda.
When they finally release Penguin version 2, you might be right. My feeling is that the long stretch means they need to do more than "fine" tuning. Unfortunately, until they do re-engineer Penguin (or at least roll out a new Data Refresh), it looks like anyone who was hit by version 1.0 is just plain hit.
However, since talk here has turned to spammy backlinks, it's good to remember that almost at the same time that Penguin 1.0 was rolled out, Google started their bad backlinks campaign with all those WMT messages and manual "actions". See our Monthly Reference [webmasterworld.com]
Those manual ranking demotions for spammy backlinks can be reversed manually, too. They are not the same thing as Penguin's "verdict" about a site.
