Hey fellows, One client has a problem - He's getting hit from January by a big xRumer submission. There are a lot of profiles pointing to his ecommerce website. Now 2 days ago, some keywords started to drop - It looks like a -50 penalty. There were already a lot of pages hit by this, but you have to consider, that there are over 10.000 other page's still ranking as before. So his site, evolved the last months to a big authority site. Yet, this happened. My suggestion was, to filter the links pointing to the site. Like all incoming links to www.domain.de who has s.th. like "member.php?" in the URL. Any other suggestions?
