It's all so disappointing because there are straightforward, objective rules that could dismiss a lot of these sites. Inform readers if the site was registered in the last 3 months, or claims to be Colorado-based but has a Bulgarian IP address, or plagiarized a bunch of articles from a different source.

It may not shut down all forms of manipulated information, but it can stymie the flow of procedurally-generated blogs that are triggering so much confusion.
