All promotion activity is pretty much artificial by definition. Google and SEOs live in the real world. High quality links can be solicited from quality blogs, relevant sites, places that give meaningful votes. I would imagine it's possible that outbound irrelevant links are being turned off. To me looking at the new backlink lists there is a discernible quality and relevance upgrade.
