Dig for it: [WebmasterWorld.com...] There is no question that Google can actively detect an inappropriate and unauthorized "pull" of the page rank value to any site. It is clear that Google intentionally leaves the "broken" algo out there to catch seo's. Many believe the last checksum code that was passed around in mid 2003 was part of what update Florida was all about. Google loves to do major updates in late fall - early winter (Florida 2003 - Dallas 2002 - Irvine 2001). I believe we are on the verge of Update Vegas. Brace yourself - I have a very strong hunch it is going to be a real hurricane.
First, the toolbar checksum was not cracked in June. It was cracked almost 3 years ago and has been continuously decoded since then. The checksum algo has changed 4 times in the intervening years.
