Take a look at the tag: CLIMATE.
A number of articles on the topic have been "hidden." These articles / content may express controversial opinions. I was not aware that "wrong-think" was hidden on Steemit. Someone (or an algorithm written for the same purpose) makes the content more difficult to find. Censorship will destroy Steemit. If I wanted some douchebag elitist in the Silicon Valley deciding what I can or cannot say on social media, I would have a Facebook account. Stop the censorship. Let the market decide what is worthy content.
