This tool for evaluating the spread of junk news on Facebook was built by the Computational Propaganda project (COMPROP) at the Oxford Internet Institute (OII), University of Oxford. Our aim in building this tool is to help researchers, policy makers, and social media platforms understand the impact of junk news on public life. We do not endorse the spread of junk news, and do not make money by aggregating this content.

This work is funded by the European Research Council through the grant “Computational Propaganda: Investigating the Impact of Algorithms and Bots on Political Discourse in Europe,” Proposal 648311, 2015-2020, Philip N. Howard, Principal Investigator, and the grant "Restoring Trust in Social Media Civic Engagement," Proposal Number: 767454, 2017-2018, Philip N. Howard, Principal Investigator. We are grateful for additional support from the Open Society Foundation and Ford Foundation. Project activities were approved by the University of Oxford’s Research Ethics Committee, CUREC OII C1A 15-044. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the researchers and do not necessarily reflect the views of the funders, or the University of Oxford.

The Junk News Aggregator was built by Mimie (Dimitra) Liotsiou. Thanks to Bence Kollanyi for his valuable contributions to the data collection. Thanks also to Lisa-Maria Neudert and Vidya Narayanan, and to the rest of the COMPROP team, for their very helpful suggestions, feedback and support during the development of this project.

Many thanks Shaun A. Noordin, Adham Tamer and John Gilbert of the OII, and Mike Antcliffe of Achromatic Security, for their valuable web development and security testing work on this project.


Using the Full Aggregator

The Junk News Aggregator shows posts uploaded by junk news sources onto their public Facebook Page. It collects posts on an hourly basis, and goes back up to one month.

You can select how far back into the past you want the Facebook posts to go ("Showing Facebook news posts from the last ... ").

You can also optionally filter results by keyword (in the "optionally filtered by content" box) or by publisher name.

In addition, you can sort by Newest or Oldest posts in the selected period, and/or by each engagement type, e.g. to get most Liked posts first. And/or you can sort by the age-adjusted version of the latter.

The age-adjusted engagement metrics offer a better way for comparing engagement levels across posts, as, due to the Facebook Graph API’s rate limits, not all posts are collected at the exact same instant. E.g. one post collected 1 minute after it was posted, another collected 43 minutes after it was posted. At most, a post may have been collected an hour after it was posted — our data collection fetches new posts from Facebook every hour on the hour. So, to adjust for this difference in post age at the time when post data was collected, we have these age-adjusted engagement numbers (they equal the number of engagements divided by the post’s age in seconds).

Using the Top-10 Junk News Aggregator

The Top-10 Junk News Aggregator is a smaller and simpler version of the Junk News Aggregator. It is not interactive, and shows the top 10 most engaged-with junk news posts of the last 24 hours, as described in the methodology.

Using the Visual Junk News Aggregator

The interactive image grid on the homepage is an image-based top-256 Visual Junk News Aggregator. It shows the 256 most engaged-with junk news posts of the last 24 hours, as explained in the methodology. Each image in this grid corresponds to a junk news Facebook post. Hovering over an image reveals a pop-up showing more information about the relevant post: the Facebook Page that posted it, the time and date posted, the text in the post, and engagement numbers. Clicking on an image takes you to the full Aggregator, where you can explore junk news in greater detail.


The Junk News Aggregator and its Top 10 and Visual versions identify "junk news" sites based on a grounded typology tested in several scientific studies conducted by the COMPROP research group. It reflects our scientific opinion and evaluation, and does not necessarily reflect the views of our funders or the University of Oxford. The basis of opinion is described in our methodology.
