When you say a site has been “shut down,” do you mean that it was removed from the search engine index, or do you mean that the site was literally shut down — i.e. the site itself isn’t online anymore. I think you mean the site was just removed from the search engine index, but I want to make sure. 
Good question I believe the site was takin off the engine, as in see you later were pulling your site off yahoo.
Honestly I think the signature thing is a dangerous. We all know alot of scrapers hang out here. Why not its like a superstore for some of the top gambling webmasters in the industry.
Pay a visit to CAP leave with a full bag of goodies. If I were a blackhatter this would for sure be the place to go.
I leave a signature, but only one. The site is mine but I would feel very sorry for the little puke head that tries to scrape it. The registrant is no other than the famous undisputed contender, Ricky G. greek39
