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.

Fact-check Feed
The Fact-check Feed site has been aggregating articles from a dozen U.S. fact-checkers since 2016 into a searchable archive. Here are the most recent:

- In his Rose Garden announcement of sweeping new "reciprocal tariffs," President Donald Trump held aloft a misleading chart that claimed to give a breakdown of the tariffs other countries charge the U.S. and the corresponding tariff that the U.S. will now impose against those countries. The post Trump’s Misleading Tariff Chart appeared first on FactCheck.org.
- Without meaningful representation, anyway.
- "The consumer confidence in this country has gone way down."
- President Donald Trump said in a March 30 interview that "there are methods" for him to serve a third term in the White House, and a Daily Mail article referred to a "loophole" in the 22nd Amendment that would make it possible. But legal experts told us the "loophole" legal argument is "implausible" and "defeats […]
- With more than 150 lawsuits against President Donald Trump’s administration, Trump and his allies are lashing out at judges — and federal Judge James Boasberg in particular. These attacks need fact-checking.
- Images show damage from an “earthquake in Thailand.”
- Do posts about a "young boy, around 3 years old," found in The Bronx express authentic concern about the child said to have been found unattended "an hour ago"? No, that's not true: The content of these posts was later...
- Are Facebook posts reporting a baby boy was found "abandoned by the roadside roughly an hour ago" in March and April 2025 genuine? No, that's not true: The posts are part of a bait-and-switch scam designed to lure social media...
- Posts on Facebook asking people to fill out a survey to access the deal are not associated with the retailer, and are not legitimate offers.
