Hello, One of my competitors have tons of links from "some" link system. Found them using yahoo's link: tool Links looks like this: http://goo.gl/OL8iU http://goo.gl/j0yxY http://goo.gl/EkBvs Links are not random. I can see links relation on pages (ie: roofing companies / builders). On the server side it looks like this: http://goo.gl/qxs2H Hundreds of randomly named (and probably generated) directories with pages with links inside. Can you please help me identify what that is? Link system or hacked server with some back-door pages (links look like carefully selected, from page to page anchors are different) or what? Thanks a ton
