One of my friends sites was hacked, apparently there was an orphaned Joomla install and the hackers must of found this older version of Joomla and inserted 2k pages of random phrases. The site is LawsuitFunding.com, a small firm that finances legal fees and expenses. If you go to Google and do a site:www.lawsuitfunding.com search you will see over 2k pages that are indexed while the actual Lawsuitfunding site only has about 30-40 pages.
The issue was brought to my attention when one of the guys noticed that they had dropped from Googles good graces and didnt even rank for their name. We have since added the site to webmaster central to see if Goog had tired to warn them, nope. We next submitted a new sitemap with the 40 actual pages and that looked to go smoothly but it has been 7 days and still the Googlebot has not made a return visit. I think we may try to pick up some links by either writing a few articles and pushing those out or doing a Press Release.
I will keep this post updated with any updated and see how long it will take to get things back up in Googles eyes.
