there is no such thing mate,
if you really want to hide your foot prints, you've to move towards white hat seo...
rather building 1000's of link using black hat seo, you're highly visible and seemed to be scammed one.
if you own a new website, you have to build links very carefully. you have to build two to three links at the starting point! when you've seen changes in your serp, just shoot your links as higher before
if you identified decent visitors, then you don't worried about penalize or something..
