My story from last week on this topic. Google shooting sites for not being able to prove things could lead to it having to do things like ban religious sites, which are built on the basis of faith. Google needs a comprehensive and defensible policy. It needs an algorithm that can better handle the increasing amount of “post-truth” content. It also needs to work on a multitude of queries, not just whatever happens to get spotted.
Finding this seemed like a process that would take several weeks, especially looking at how Google had dealt with similar type issues. For example, it took weeks after concerns about “content fax number list farms” escalated for Google to develop its Panda Update filter to filter low-quality content from its results. Google moved much faster here. It remains to be seen whether the short-term solution is sufficient.
Sometimes I can always see the denial page listed first. Other research I have reviewed may still have terrible results. We will have a better idea in a few days, when the new algorithm is installed in all Google data centers.
