The report said that the social media giant last year created an algorithm to identify pages that would affect the most publishers — instead of using Facebook's long-established database of existing news publishers. "If 60% of [sic] more of a domain's content shared on Facebook is classified as news, then the entire domain will be considered a news domain," stated one internal document, as per WSJ.

The Journal reported that the tech giant not only took down pages for media outlets but also removed pages for hospitals, governments, and charities, just as the country was launching Covid-19 vaccinations.

Meanwhile, the company has maintained that blocking the government and healthcare pages was accidental and told WSJ that "the documents in question clearly show that we intended to exempt Australian government Pages from restrictions in an effort to minimize the impact of this misguided and harmful legislation."

The whistleblower's documents were filed with the U.S. Department of Justice and the Australian Competition & Consumer Commission, and a number of members of the U.S. Congress were also reportedly given copies.
