After I reported the serach engine SPAM to yahoo, google and MSN, when the SPAM sites will be removed?

My name search results have linked to porn site and I want the search engine company to remove them. I have reported to the forms provided by the sites but there is no response. I also want to know how long when the SPAM sites in my search will be removed?

You can clear your search history on your own. As far as the site itself, it will be diverted in the future, but they aren’t removed from your history. They may drop out on RAM overflow, but if you want them removed, you do it.
