A collection of tools that monitor misinformation: Iffy Quotient social media tracker, CoVaxxy tweet chart, NewsWhip top-25 Facebook publishers table, Fact-check Feed aggregator, and this plot of Factual Grades for 245 major news sources by The Factual.
Iffy Quotient: Facebook, Twitter
The Center for Social Media Responsibility (University of Michigan) maintains the Iffy Quotient (not affiliated with this site), a measure of the low-credibility content amplified on Facebook and Twitter, based on trust-ratings by Newsguard and Media Bias/Fact Check). This graph charts the percentage of top 5K social media posts that link to unreliable sources:
Content from “Iffy” sites amplified on Facebook and Twitter
Another way to express their data is "an engagement-weighted version of the Iffy Quotient. Rather than treating all popular URLs as equal, we weight them by the estimated engagement scores."
NewsWhip: Facebook
NewsWhip "tracks and predicts the impact of millions of stories." The chart below uses their API to rank the top 25 publishers by their engagement on Facebook. (English-language content, ranked by number of articles, by likes, shares, and comments for total engagement, grouped by domain; does not include media uploaded to Facebook.) The factual column is the publisher's factual-reporting level, as rated by Media Bias/Fact Check.
