How social media platforms are fighting coronavirus misinformation

The illness,COVID-19, caused by the novel coronavirus has put pressure on social media platforms to try to deal with floods of misinformation.

Even getting a handle on the size of the problem is tricky because while social platforms are publicly keen to tackle the problem, they're less forthcoming with numbers that might show how much false information is circulatingand how they're working on the problem.

It's clear that coronavirus is a hot topic. In a blog post on Jan. 29, Twitter revealed it had seen over 15 million tweets on coronavirus over the previous four weeks. A brief look at Google Trends shows that coronavirus searches began to grow in Canada around Jan.18and spiked on Jan.31, though it's not possible to determine exact numbers.

One way to get an ideahow much false and misleadinginformation is circulating is by looking at what the fact-checkers are facing.

An internal spreadsheet compiled by the International Fact-Checking Network documents over 370 coronavirus-related debunks done by fact-checkers and journalists around the world since Jan.22. The IFCN was started in 2015 by the Poynter Institute, a non-profit journalism training organization, and brings together fact-checkers around the world to share information and establish best practices.

Louis Baudoin-Laarman, a fact-checking journalist with the wire service Agence France-Presse who focuses on Canada and the U.S., says he estimates the wire service has already done between 30 and 40 debunks around the world in just the past two weeks.

AFP is one of the third-party fact-checkers partnering with Facebook, which means once an AFP journalist has written a story and flagged that a particular piece of information is false to Facebook, the platform will take steps to limit that information's spread and to surface correct information instead.

Baudoin-Laarman says he finds that COVID-19 misinformation falls under four main categories:

• false information about cures;
• false information about where new cases are being discovered;
• images or videos purportedly showing people who are sick or falling over from coronavirus;
• false information about the origin of the virus.

Removing content

In a blog post on Jan. 30, Facebook said it would begin to remove content containing conspiracies or false claims that had the potential to cause physical harm to users, such as incorrect medical information.

When contacted by CBC News, a Facebook Canada spokespersonwas unable to reveal any figures about how much content may have been removed.

In Twitter's Jan. 29blog post, the service noted it had taken steps to ensure the platform was protected from "malicious behaviours" and that it would remove accountsengaging in those behaviours.

• Online claims that Chinese scientists stole coronavirus from Winnipeg lab have 'no factual basis'
• Dubious screenshot claims Chinese website published 'real' coronavirus death toll

The most high-profile instancecame when Twitter permanently suspended the account of Zero Hedge, a far-right site that purports to share finance and economic information, for circulating a theory blaming one Chinese scientist, without evidence, for creating COVID-19.

Buzzfeed reported that Zero Hedge had posted the personal contact information of the scientist online, a practice known as doxxing, and encouraged others to get in touch.

Twitter hasn't revealed how many accounts it may have banned. A week after the coronavirus post, Twitter also announced it would remove or label deepfakes videos altered using AI to make it seem as if someone said or did something they didn't and other deceptively altered content that could cause harm. (Facebook announced at the start of January it would ban deepfakes.)

Google and YouTube did not provide information about removing content or altering search results but did provide information about a special search alert set up for the novel coronavirus.

Partnerships with health organizations

Facebook, Twitter and Google haveprioritized links, pop-ups or search resultsdirecting users to information from official health partners like the World Health Organization and the Public Health Agency of Canada.

The WHO itself has a page dedicated to myth-busting claims about the virus. Some of the claimson the WHO site include whether hand dryers can kill the virus (they can't), if it's safe to get a letter or package from China(yes) and if putting sesame oil on your skin will protect you from coronavirus (no).

When Canadians search Twitter in either official language for coronavirusinformation, the first result they'll see is a tweet from Dr. Theresa Tam, Canada's chief public health officer, directing users to a page with up-to-date health information.

Anna Maddison, a spokesperson for Public Health, told CBCNewsthat the agency worked with Twitter in May2019 on a #KnowTheFacts notification to direct Canadians to factual information on vaccines.

"The government of Canada applauds efforts by social media and technology companies to increase access to evidence-based information on their platforms," Maddison wrote in an email.

On YouTube, Instagram, and Facebook, users who search for coronavirus information may see search results or pop-ups directing them to the World Health Organization.

However, Facebook still may surface information that is less relevant to users. A recent search by CBC News included results from news organizations, but also links to an event listing called 'Carnaval Coronavirus' Brazilthat appears to be a joke, and a link to a public health event in Sweden.

On Instagram, users may first be directed to accounts that purport to aggregate coronavirus newsbut aren't associated with any media organization, or even virus meme accounts, without seeing a pop-up directing them to the WHO.

On Google, users first see recent news related to COVID-19 but are also directed to the World Health Organization for more.
