Pinterest Has A Bogus Health News Problem


Pinterest is where many people turn for ideas about how to be healthy. But the recipes, nutrition advice, and other colorful infographics that the site is so well-known for are rife with bad information about health and science.

Pinterest is where many people turn for ideas about how to be healthy. But the recipes, nutrition advice, and other colorful infographics that the site is so well-known for are rife with bad information about health and science.

This kind of misinformation is baseless and ineffective at best, and harmful at worst — some pins, for example, make unsubstantiated claims about preventing and treating cancer — but Pinterest says that it is only a minor problem for the site.

With little effort over the past month, BuzzFeed News found more than a dozen misleading health-related pins that were being shared widely.

One pin, saved to about 13,000 boards, falsely claimed: "Even Doctors Can Not Explain This: Boiled Cinnamon And Honey Is The Cure For Many Health Problems," from cancer to arthritis to gall bladder infections. Another pin with a bogus claim — "Retired Pharmacy Chief Said: 'The World Needs To Know, Alkaline Water Kills Cancer'" — was saved to more than 16,500 boards.

One pin, saved to 16,000 boards, suggested in its title that "vitamin B17" could be a "cancer treatment." But that's a nickname for a chemical compound that is not an officially recognized vitamin and does not cure cancer. In fact, large doses can generate dangerous or even fatal levels of cyanide.

The title of yet another pin claimed that genetically modified foods are "Linked to Tumors, Allergies and Early Death," which is not supported by scientific evidence. It was saved to about 15,000 boards.

Some of the dozen or so false or misleading health pins that BuzzFeed News found were removed after we contacted Pinterest and the authors of the pins for comment. Pinterest said that it took action on the pins that violated its terms of service.

Misinformation on Pinterest isn't just limited to health advice: Earlier this month, the Washington Post also reported that the site had been flooded with political content created by Russian operatives in an attempt to sway the 2016 election.

Adelin Cai, head of policy at Pinterest, told BuzzFeed News that a "small volume" of medical misinformation exists on the platform, although she did not know what percentage of the overall content it comprised.

"We have so much content on the platform. It's curated by millions of people across a variety of categories," Cai said. "Sometimes those ideas might be controversial or cause some public concern, or they just might not be for everyone."

She added, "At the end of the day, what we're really concerned with is making Pinterest a really safe place so people can find and discover the things they really love."

Pinterest largely relies on users to report problematic content, Cai said.

Pinners can report individual pins by clicking on them and selecting from reasons like "I don't want to see this," "This is spam," and "This goes against Pinterest's guidelines." From there, Cai's team can decide whether to delete a pin or make it "undiscoverable," which means that it still exists on a person's board but that other users cannot search for it.

In its guidelines for community posters, Pinterest says it removes content that "promotes harmful behavior."

One type of that content is "medical misinformation." The company says, "We'll take action on content spreading medical misinformation that could lead to serious harm to Pinners – for example, claims of curing diseases currently considered by the medical community to be incurable." Cai said in an interview that this list includes cancer and epilepsy. (She added that advertisers are not allowed to promote medical misinformation.)

But Pinterest's definition of medical misinformation overlooks other forms of unsubstantiated health information.

One pin, for example, linked to a raw apple cider vinegar recipe, claiming it could cure urinary tract infections.

One pin, for example, linked to a raw apple cider vinegar recipe, claiming it could cure urinary tract infections.

In the text of the pin, the author claimed, "Find out how to get rid of bladder infections naturally! Yes, without a doctor and without antibiotics! It is easy and really works!" Although home remedies can help ease the discomfort of UTIs, the most effective line of treatment is antibiotics, and letting UTIs go untreated can lead to more severe kidney infections.

Dina Marie Oswald, who runs MyCulturedPalate.com, defended that recipe to BuzzFeed News, saying that people should try natural remedies before resorting to traditional medicine. "There's nothing on My Cultured Palate that I have not personally used," she said. "These are things that really work."

A different pin claimed that genetically modified foods "have not been proven safe," even though studies have overall concluded that they are as inherently safe as conventional foods. Both pins are still up.

"When content comes to us, we will consider it and see whether we consider it appropriate for the platform or not," Cai said, when presented with these types of examples. "We make tweaks internally and publish things externally if we change our policies."

Some of the people who've made these misleading health pins admit that the claims they make aren't always valid.

Josh Axe, who runs the natural health website DrAxe.com, is a self-described "doctor of natural medicine, doctor of chiropractic and clinical nutritionist with a passion to help people get healthy by using food as medicine." Infographics that the site posted on Pinterest, and linked back to his website, suggested that "vitamin B17" was a potential "cancer treatment" and that genetically modified food is linked to leukemia, liver toxicity, kidney failure, and gut inflammation.

A DrAxe.com spokesperson said his team had removed the pins after BuzzFeed News inquired about them. "Some articles on our site are older and don't contain the rigorous, accurate research that we've become known for," spokesperson Alex Loria said by email. "The GMO and the 'Vitamin B17' articles you point to are both faulty in some respects and have been taken down while they are reworked."

And Anne-Marie Nichols, a lifestyle and recipe blogger in Georgia, has pinned the popular infographic that claims that genetically modified food is not safe — even though she says she no longer believes that's true.

Nichols told BuzzFeed News she posted the infographic, which was supplied to her by an outside company, on her Pinterest and her blog, This Mama Cooks, three to four years ago.

She's since deleted it from her blog, but it's still on her Pinterest, where it's been shared to more than 26,000 other boards. Nichols said that she has pinned thousands of images over the years — sometimes the same image multiple times in an effort to get pinners' eyeballs on it and drive traffic back to her blog, which is a common practice on the platform, she said. With Pinterest's user interface, it's hard even for her to find her own content.

"These boards are so gigantic, I couldn't go find it without scrolling and scrolling and scrolling," she said.

Some users say that even though Pinterest is an increasingly difficult place to capture people's attention, the website referral traffic is still too significant to be ignored. Health pins can help drive that traffic.

For example, a pin containing a juice recipe to cure a UTI "without antibiotics" has been saved to 37,000 boards. It was created by Lee Traister, who says Pinterest is her top source of traffic to her site ladyleeshome.com.

Traister told BuzzFeed News that Pinterest generates about 50% of the 50,000 to 70,000 monthly page views she gets on her site dedicated to homestead living. "I also post regularly on Facebook," she said. "But Pinterest is by far the greatest for bloggers in this niche as far as traffic goes."

Asked about the scientific basis for the claim that her juice recipe can cure a UTI, Traister said that a lot of commenters have said the recipe worked for them. But "every person is going to have to decide for themselves what they want to try," she said.

Here Are Some Of The Facebook Ads Linked To A Russian Troll Farm

The House Intelligence Committee released on Wednesday a sampling of the Facebook ads linked to a Russian troll operation during the 2016 presidential election.

The committee also released the names of some Twitter accounts that were linked to the targeting.

The ads were released during the House committee's open hearing with representatives from Facebook, Twitter, and Google on how their platforms were used by Russia to interfere in last year's election. The committee is led by Rep. Adam Schiff, a California Democrat, and Rep. Mike Conaway, a Texas Republican, who has led the committee's Russia probe since Chairman Devin Nunes stepped aside from the investigation.

Facebook has previously said a portion of the ads were targeted by location. In at least one case, an ad referencing Black Lives Matter was targeted toward people in Baltimore and Ferguson, Missouri, which have both seen violent clashes in recent years following the deaths of unarmed black men at the hands of police.

Facebook revealed in early September that fake accounts and pages linked to Russia spent approximately $100,000 on political ads during and after the last presidential campaign. Most of the ads, Facebook said, didn't necessarily mention specific candidates. "Rather, the ads and accounts appeared to focus on amplifying divisive social and political messages across the ideological spectrum — touching on topics from LGBT matters to race issues to immigration to gun rights," Facebook said.

Facebook subsequently turned over the more than 3,000 Russian-linked ads to congressional committees investigating interference in the 2016 campaign.

While the Senate Intelligence Committee has maintained it has no plans of releasing the ads, the Conaway and Schiff said in October that they were working with Facebook to delete personal information from the ads, with the aim of releasing them publicly after the hearings in both the Senate and House Intelligence committees with representatives from Facebook, Twitter, and Google.

It is illegal for foreign entities to make contributions in US elections, but a lack of rules around online political advertising means the Russian ad activity could go mostly undetected. In the Senate, three senators have introduced a bill that would increase transparency around ads on Facebook and other websites. Facebook has also announced measures to increase transparency around paid political ads.

Some Senate Investigators Say They Now Want To Hear Directly From Twitter, Facebook And Google CEOs

Several Democrats on the Senate Intelligence Committee want to hear directly from the CEOs of Facebook, Twitter and Google, following a frequently tense hearing with lawyers from the companies on Wednesday that they said offered few satisfying answers about Russia’s use of their platforms to influence US politics and how they’ll prevent foreign interference in the future.

Both during and after the hearing Wednesday, Democrats on the committee said they will make the push to hear from the CEOs — Twitter’s Jack Dorsey, Facebook’s Mark Zuckerberg and Google’s Sundar Pichai — in the near future.

Independent Sen. Angus King, of Maine, made a point during the hearing of asking the companies’ general counsels to tell their CEOs that the Senate would like to hear from them.

“Gentlemen you’ve done a good job this morning, I must say though, I’m disappointed that you're here and not your CEOs, because we're talking about policy and the policies of the companies,” King told the witnesses. “And it's fine to send general counsel, but I think if you could take a message back from this committee, if we go through this exercise again, we would appreciate seeing the top people who are actually making the decision.”

Democratic Sen. Ron Wyden said after after he left the hearing that he wants to hear from the CEOs themselves because he was disappointed in the answers members received Wednesday. “We didn’t get any specifics when I asked them what they were going to do to promote real changes, so I feel very strongly about this,” Wyden said.

Asked when he would want the CEOs to come in, Wyden said, “as soon as possible.”

The committee’s leaders, however, are still considering whether dragging the CEOs in for follow-up testimony is the right move.

Virginia Sen. Mark Warner, the leading Democrat on the committee, said he was frustrated with what he heard on Wednesday. “Considering how long this hearing was in the making, I was pretty disappointed that, for example in the case of Facebook, that they seemed to not to have identified much beyond their initial search,” Warner said, adding: “I’ve got more questions.”

"I think it would have been more fruitful” to hear from the CEOs themselves, Warner said. But when asked if that meant he would join his colleagues in making a push for them to testify, Warner added: “I want to actually reflect on that a little bit before I give you a straight answer."

North Carolina Sen. Richard Burr, the chairman of the committee and Warner’s Republican counterpart, also said he’d need to think over the idea of asking the CEOs to come before the committee. “Oh listen, we just finished [the hearing] three minutes ago, so give us time to sort of think through it,” Burr said.

But while Warner and Burr consider their options, several Democrats on the committee say they see bringing in Dorsey, Zuckerberg and Pichai as a necessary next step — including both California senators, who represent the companies’ home state.

“I think that at some point, we’re going to have to get information from the people who lead policy, and not just the top lawyers, about what their policy’s going to be, what their priorities are going forward,” California Sen. Kamala Harris told BuzzFeed News. “And to the extent that CEOs make policy decisions, then we’re going to have to hear from them.”

Asked if she was hopeful that Republicans would also want to hear from the CEOs, Harris said: “From the questions that both sides asked today, that’s my impression that that would be what they want.”

“I understand why they send the chief counsel out ... but it doesn’t solve the problem of having the person that’s responsible hearing the concerns firsthand,” California Sen. Dianne Feinstein said. “The question comes, for me, I represent them, I’d like very much to sit down with the CEO and, you know, have a conversation about this.”

Feinstein noted, however, that she thought the counsels had given better answers at Wednesday’s Intelligence hearing than at a Judiciary committee hearing she attended the day before.

While Republicans on the committee haven’t expressed a strong desire to hear directly from the CEOs, they also have not shut down the idea.

Oklahoma Sen. James Lankford, a Republican, argued that the committee wasn’t likely to get different answers from CEOs than from the general counsel.

“It really doesn’t matter to me one way or the other,” he said. “The CEOs will talk to their counsel on any statement that they’re going to make anyway, so getting a direct access to their counsel I think is also helpful, either one, to be able to communicate the position of the company I think is fine.”
