That is exactly my thinking. I don't see how it's fair to penalise for things that may have happened many months/years ago such as the building of 'dodgy' backlinks. Surely there must be some component of this algorithm change that looks at how recently such backlinks were created. Perhaps that hasn't kicked in yet? If not this is a complete and utter unjustifiable crock of s*** that Google has just created.
