Seems to be 'stuff that the mainstream media doesn't cover or want you to know' rather than fake news.

From the about page: 'The Quibbler aggregates relevant news flagged as "fake news" by the media. It also provides links to corresponding Reddit discussions. It works by using "fake news" lists like the ones published by Washington Post. It also uses lists of news that is removed from social media.'

Looks like mostly fake news to me, with some real news from shady sites mixed in.
