Known as -60 Penalty, it pushes the website of the penalized Webmaster 60 positions back in the search pages. This penalty is enforced mainly in the case of Paid Links, as they are considered to a be questionable tactic to gather links.
According to Search Engine Roundtable, it seems that Google is finally admitting to use of -60 penalty. There has been an ongoing thread in Google Groups regarding Google’s use of -60 penalty, where Googler JohnMu has replied in a most nonchalant way, not addressing the -60 penalty issue directly but giving tips to cleaning up the site from a spam perspective.
