If you think about it, the only links that are natural are those not asked for and anything else is not natural because you are doing it to rank higher. Think of your link building plan as marketing rather than building links to rank higher. For example, if you post articles in niche article directories, do so to get people hooked to your site and not for the purpose of a cheap link back to your site that invariably people do (in the resource box). This way you will eliminate lot of the bad practices in linkbuidling campaigns. Most importantly, though, write content that you yourself wouldn't mind linking to if it appeared on someone else's site. In other words, top notch content.
