OK so I know google have said check your back link profile for anything dodgy looking and remove it if so with our disavow tool. So now they've given us this feature they're free to go ahead and penalise sites that have just spammed their money site. How ever they cant expect us to check the back link profiles of tiers of links ! So for example I might have an awesome web 2.0 pointing to my money site but 100k of spam pointing to the web 2.0. Google can't penalise people for that if they detect it can they? Because how are legit webmasters (white hat) meant to detect that!? Hopefully you can see my point? They can't penalise people for something they can't defend agaist/detect and therefore we can exploit this?
