Anti-vaxx propaganda has become viral on Facebook. Pinterest has improved Technology


On Wednesday, Adam Schiff, a powerful committee chairman of the House, he joined journalists From around the world in Meme Twitter event: search "vaccine" on Facebook and posted a screenshot of the results.

Schiff search results were really scary: automatic suggestions for phrases such as "vaccination post-education discussion forum", group of "Parents Against Vaccination" group, and page for the National Information Center on A doctor, an official sounding organization that propaganda a propaganda antibody. And while search results on Facebook are personalized to all users, the recent Guardian's recent report found similar results in good faith for a brand new account.

If the congress had tried to search "vaccines" on the Pinterest Pinterest social social media website, however, it would not have been much more for a screen or a white screen. Recognizing that search results for a number of terms related to vaccines have been broken, Pinterest "broken" responded to its own search tool.

As pressures on Facebook tackle its role in promoting illegal information, Pinterest offers an example of a different dramatic approach to the management of remote health information on social media.

"We are a place where people are coming to find inspiration, and nothing is inspirational for harmful content, says Ifeoma Ozoma, a policy manager and social society on Pinterest." We think we are not on # 39; n platform for that. "

Last week, I wrote to Facebook and Google to express my concern that their sites steer users to poor information that encourages vaccinations, undermining public health.

The search results you get for "vaccines" on Facebook are dramatic illustrations.

This has not always been the case. Scrutiny faced the visual social network in 2016 after a scientific study that 75% of vacancies related to vaccines were negative. Next year, Pinterest updated its "community guides" to specifically exclude "the promotion of counterfeit chronic illnesses or chronic illnesses and anti-vaccine advice" under a wider policy against misunderstandings that "have adverse effects on health penalties or on the public safety ".

The policy change clears the way to Pinterest using a number of technological methods to go to anti-vaxx politaganda. The company has banned boards from a number of prominent anti-vaccine propaganders, including the National Vaccine Information Center and Larry Cook, who run the website and Facebook group "Stop Mandatory Vaccination".

But only one aspect of the company's approach is to enforce retrospective content rules.

Take search results. The phenomenon that is displayed in the Facebook search result screens is known in technology circles such as "empty data", after a paper by the Data baseer and the Society and the Danah researcher boyd. For some search terms, boyd explains, "the relevant data available is limited, that does not exist, or is a bad problem".

In the case of vaccines, the fact that scientists and doctors are not generating constant numbers of new digital content for fixed science has left vacant for plot theory and fraudulent thieves to fill propaganda and remote information.

Data vacancies may be relatively easy to diagnose, but they are very difficult to solve.

"Tackling data spaces can not be achieved by removing problematic content, not just because it could move against the aims of search engines but also because it would not be effective," said Boyd. "Excluding high quality replacement and content that has been removed, new malicious content can easily face".

Pinterest has responded by building a "blacklist" of search terms "corrupted".

"We do our best to get rid of poor content, but we know there is poor content that we have not yet arrived," explained Ifeoma Ozoma, a public policy and social impact manager at Pinterest. "We do not want to face that with search terms such as cancer or suicide improvement.We hope we can move from the site break to only face good content. That's better. "

Pinterest also includes images of a misunderstanding of health in its "hash bank", preventing users from refining anti-vaxx memps that have already been reported and taken down. (Hashing is a technology that is a unique digital identifier for images and videos; it has been used more widely to prevent the spread of child abuse images and terrorist content.)

And the company has banned all pins of specific websites.

"If there is a dedicated website altogether to spread health information, we do not want it on our platform, so we can stop the URL level," said Ozoma.

Users can not "ping" a link to or the "alternative health" sites, and; if they try, they receive an error message setting out "invalid parameters".

Pinterest does not report free. The Guardian was able to find a vaccine propaganda on the site by searching for different terms that were not listed on the blacklist, such as "MMR", the vaccine against measles, scallops , rubella

Ozoma said that a challenge was how much anti-vaxx material is being transmitted from what he describes as "large social media platforms and large video platforms", rather than by Independent websites, as Pinterest does not want to break all oversubscribed content by Facebook or YouTube.

"This has not been a focus for other platforms, says Ozoma." We've been working on this since 2017, but we have been kind to ourselves. I hope that more discussion will go on. "
