Editor’s Note: The Washington Post on Nov. 24 published a story on the work of four sets of researchers who have examined what they say are Russian propaganda efforts to undermine American democracy and interests. One of them was PropOrNot, a group that insists on public anonymity, which issued a report identifying more than 200 websites that, in its view, wittingly or unwittingly published or echoed Russian propaganda. A number of those sites have objected to being included on PropOrNot’s list, and some of the sites, as well as others not on the list, have publicly challenged the group’s methodology and conclusions. The Post, which did not name any of the sites, does not itself vouch for the validity of PropOrNot’s findings regarding any individual media outlet, nor did the article purport to do so. Since publication of The Post’s story, PropOrNot has removed some sites from its list.
WaPo has literally disclosed this and the story itself is not even fake news, it has questionable sources. Did you even read the article?
