Some asshole hacked into my site and created a bunch of fake pages on my domain. Then he started linking to those pages using anchor text such as Casino, drugs, porn, etc. The thing that is puzzling me is, the pages created are like this: [domain] fgdfrdfshdb-? and some more gibberish. When I go to the link, I can see its hosted on my site. However all of the new pages the asshole created on the domain have now been set to no-index in Google webmaster tools. He created 1,533 pages but since they all use the same 'fgdfrdfshdbz' text in all the links, I was able to set the URL parameters as "no crawl" so they are not indexed in Google. So far my site has not been indexed and traffic is normal. But as you can see in the screenshot this asshole has been steadily building links to my site. My question is, should I be worried about these links since they are linking to pages that are not indexed in Google?
