As much as I dislike fox news (and virtually all news orgs now) they're probably among the only people actually tracking things like this. I understand if you dislike their political message, but the links the other commenter provided are all good examples of specific instances of the censorship we're discussing. That the organization as a whole is incredibly biased doesn't alter the fact that the people in those stories were actually silenced.

The fact that you can't easily find any record of these events outside of Fox News is a part of the issue and "mass scale" censorship.
