noindex tag to deleted threads and that tells Google to remove the page from their index. The page is still visible if you know the URL, and not all search engines respect noindex directives as well as Google. We can't claim that a deleted thread is off the public Web permanently, but once a page is gone from Google it is gone for most people.
