I run an italian site that's in the top 50k of alexa. I discovered 3 weeks ago that our site was linked back by a ton of domain registred with italian soundlike name, all of that registerd in the us. Different name, same technique, a web page with related keyword and url website related to that keyword, a garbage! I was expecting pr in these update, nothing, no change. Before the update or, i dont know, before these spammer use our url, the site had backlinks on G. Now, no backlinks. Some domain of these spammer are no more visible on G, but some others are still indexed. I think G put in a limbo all the site involved in some spam action until they drop these spammers from the index. Someone in the same situation? Any idea?
