Well, the problem is that you are searching on fox news of all things.

EDIT: To make my comment a bit less argumentative, here is a good chart on the biases of media outlets: https://my.lwv.org/california/torrance-area/article/how-reli... , scroll down to adfontes.

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.

Fox news, and other right-wing outlets, are the only ones who will report truthful negative stories on media companies or politicians that are Democratic party aligned. The centrists closed ranks as a result of what they consider the twinned media failures of Corbyn and Trump. They simply agree as a group not to report on things that are potentially damaging to Democratic centrist candidates or agendas, because they feel that truthful reporting is what sank H. Clinton.

Any of them will explain to you how reporting the facts created a false sense of equivalence between Clinton and Trump for voters. Voters couldn't understand how Trump bragging to a frat boy reporter that he could just grab pussy, his using a nonprofit as a vehicle to dodge taxes on a painting, and his denial that McCain was the best hero were far worse than the 1994 Crime Bill, superpredators, Clinton Foundation associations with dictators, the Iraq War, Russian uranium, Haiti, and Honduras.

That’s a fair criticism. I was looking for examples for my comment and knew that would be a good source for them knowing they are mostly politically right leaning. I just went to cnn.com to get some examples from them to kinda even it out for you. I used the same search criteria “twitter censorship”. I didn’t find a good example in the first 14 pages of search results.
