Google just released a new algorithm just to remove Googlebombs the first one to go was Bush's "miserable failure" or "failure". People are starting to get worried however if this will affect normal sites that just happen to get thousands of links with the same anchor text. Especially sites in a seo contest. As google suggest its a algo update they probably may have done the things to get no value to click here links also and that can effect the others websites also.
