And I totally agree with you. I would like to add that some people are just pushing posts out there of which many are plagiarized. Fake news in regards to the Status ICO was even upvoted more times then my article about it lol.
However, I believe that like Wikipedia there can be a community that manages itself with some trusted curators that can block upvoting on an article and possibly even change or remove an article. Removing an article might sound drastic but at times I have seen the same article, copied from another website, being posted by multiple people.
