There's a lot in the media about "fake news" at the moment. One thing that is helping it are the sheer number of people who link to it, often with noble intentions of warnings or analysis. A side effect however are the positive effects the high authority links will have on SEO. If you want to link to fake news, nofollow your link. This may not be best practice or etiquette, but then neither is fake news.
I was actually shocked to see that the article, “Obama Signs Executive Order Banning The Pledge Of Allegiance In Schools Nationwide” had a Trust Flow of 38 and a Citation Flow of 39. I then looked into the Backlinks section of the particular URL and found out that the reason why this article had such high FlowMetrics was because the majority of his top links were of highly reputable sites linking to the article, warning their readers about the dangers of fake news and how to avoid it.
