This will only compound your problem.. they just want to clean up the spam sites showing up in the first page.. I commented on google webmaster blog about the spam links and zero content sites topping the search results (those sites were there for months) and the next day after posting the comment, those sites were removed.. this is not going to help us.. there is no way they can manually check all the sites.. it is just for removed of spam links.. they created the mess, let them fix it themselves
