Wondering if this is somehow possible. A site got hacked and created a /data folder with hundreds of .php files that are web pages selling all sorts of stuff. We deleted the /data folder and blocked Google from indexing it. Just noticed in Webmaster Tools that the site has 35,000 backlinks from other sites that got hacked with the same way. Is there a way to block these sites? I am assuming there isn't, but wanted to see if anyone ran into the same problem. It is a wordpress site is that helps.
