I begin to think about how to build a linter/scorecard for this sort of stuff.

Example linter rules:

  This article does not have a source.
  This article has no sources from a known resource [this community] find reputable.  
  This article has a source from a source known to this community to be non-reputable.
  This article has a "shallow" source such as a blog (tumblr, medium, blogspot, youtube)

Probably would need a mechanism to build/aggregate/crowdsource reputable source lists.
