Some anti-vaccination groups on Facebook are changing their names to euphemisms like Dance Party or Dinner Party, and using code words to fit those themes in order to skirt bans from Facebook, as the company attempts to crack down on misinformation about Covid-19 vaccines. The groups, which are largely private and unsearchable but retain large user bases accrued during the years Facebook permitted anti-vaccination content, also swap out language to fit the new themes and provide code legends, according to screenshots provided to NBC News by multiple members of the groups. One major dance party group has more than 40,000 followers and has stopped allowing new users amid public scrutiny. The backup group for Dance Party, known as Dinner Party and created by the same moderators, has more than 20,000 followers. Other anti-vaccine influencers on Instagram use similar language swaps, such as referring to vaccinated people as swimmers and the act of vaccination as joining a swim club. A Facebook spokesperson declined to comment but pointed NBC News to the company’s efforts to drive users to authoritative sources on Covid-19 vaccines. The ban-evasion maneuvers by anti-vaccination groups on Facebook and Instagram are ratcheting up as the White House has increased pressure on the social media platforms to do more to contain vaccine misinformation and disinformation. Biden calls on Facebook to stop spread of ‘outrageous misinformation’ about Covid vaccines JULY 19, 202101:28 They’re killing people, President Joe Biden said Friday about vaccine misinformation on Facebook, later softening his language to say he hoped the platform would do more about outrageous misinformation. Facebook spokesman Kevin McAlister responded Saturday: The facts show that Facebook is helping save lives. Period. The back-and-forth was not lost on people in the anti-vaccine groups. In a post with more than 4,000 reactions and 1,000 comments, an administrator of Dance Party mentioned that the WH press had a press briefing and mentioned a few notable groups that had been closed and some that are beating the bot system. Beating Facebook’s moderation system feels like a badge of honor, the administrator wrote, followed by a crying-laughing emoji. At the end of the post, the administrator reminded users to stay away from unapproved words, and pointed them to a code legend on the side of the page. Using code words to evade bans is not new among the anti-vaccine community, and it borrows from a playbook used for years by extremists on Facebook and elsewhere. The practice leans heavily on leetspeak, or modified language used by coders and gamers that frequently replaced letters in words for numbers or symbols during online discussions.

This is part of the culture of anti-vaccination activists. Group members have incorporated a range of coded language to mask their discussions, many of which perpetuate debunked theories about the vaccines. Danced or drank beer mean got the vaccine. References to Pfizer generally use the terms pizza or Pizza King, and Moderna is referred to as Moana. Users generally play around with unofficial language about dancing to create more coded language. For example, one group member said her husband had become sick after going on a cross country trip where we spent 2 nights with dancers, referring to two people who had just been vaccinated. He believes that by being around those who have danced the glitter caused the shingles reactivation, the group member wrote. The glitter, in this case, refers to vaccine shedding, a false theory among anti-vaccine activists that claims people who have been vaccinated are somehow shedding their vaccine onto the unvaccinated, and causing them to become sick with a litany of illnesses. The use of coded language underscores the challenge Facebook has in containing anti-vaccine sentiment that built up for years on the social network and other digital platforms. Facebook began to crack down on vaccine misinformation in 2019 and pledged in 2020 to take swift action against Covid misinformation Other extremist groups have been found to use coded language in an effort to avoid detection. The anti-government boogaloo movement derives much of its iconography from alternative names used to preventively skirt Facebook bans. The group’s members wear Hawaiian shirts and patches depicting igloos because some of the largest boogaloo Facebook groups changed their names to Big Luau and Big Igloo in advance of the group’s expulsion from Facebook. Donovan said extremist groups change their names to banal or unoffensive-sounding names during increased public scrutiny in an effort to retain the audience they’ve built up. After Charlottesville, white supremacists were scrambling to change the names of their groups to things like Muslims for Peace. In doing so, they’re obviously participating in ban-evasion, but they’re learning to work better together, she said, referring to the deadly 2017 Unite the Right rally in Virginia. There’s a network effect there where people are imagining themselves as being persecuted and having access to some secret knowledge.

As a deadly heat wave scorched the Pacific Northwest last month, overwhelming hospital emergency rooms in a region unaccustomed to triple-digit temperatures, doctors resorted to a grim but practical tool to save lives: human body bags filled with ice and water.

Officials at hospitals in Seattle and Renton, Washington, said that as more people arrived experiencing potentially fatal heatstroke, and with cooling catheters and even ice packs in short supply, they used the novel treatment to quickly immerse and cool several elderly people.

Zipping heatstroke patients into ice-filled body bags worked so well that it could become a go-to treatment in a world increasingly altered by climate change, said Dr. Alex St. John, an emergency physician at UW Medicine’s Harborview Medical Center.

I have a feeling that we’re looking at many more days of extreme heat in the future, and this is likely to become more common, he said.

Despite the macabre connotation of body bags, using them is a cheap, convenient and scalable way to treat patients in mass casualty emergencies caused by excessive heat, said Dr. Grant Lipman, a Stanford University professor of emergency medicine. He co-authored a pioneering case study documenting the use of what doctors call human remains pouches for heatstroke.

When people are this sick, you’ve got to cool them down fast, Lipman said.

Heatstroke, the most dangerous type of heat illness, is a medical emergency that leads to death in up to a third of hospitalized patients. It occurs when the body overheats, either because of exertion in high temperatures or because of prolonged exposure to heat with no relief. The core body temperature rises to 104 degrees Fahrenheit or higher, which can damage the brain and other organs.

Heatstroke can be particularly dangerous for children and older people, whose bodies don’t regulate temperature well. In addition, elderly people may take medications that impair their ability to tolerate high temperatures.

Patients typically would be treated with strategically placed ice packs or misted with water and placed in front of huge fans. Some emergency room staffers immerse patients in large tubs of water or insert cooling catheters into the body’s large veins.

During emergencies, however, equipment, ice and time may all be in short supply.

Every hospital has body bags. Every hospital has ice machines.

St. John treated nearly two dozen heatstroke patients on June 28, the hottest period of a six-day heat wave, when temperatures in Seattle shot to a record 108 degrees. That was more than he’d seen at one time in his decade as a doctor, including working in hospitals in the Arizona desert, he said.

Similarly, UW Valley Medical Center in Renton treated more than 70 patients with heat-related illnesses, three of whom who were treated using body bags, said Dr. Cameron Buck, director of the emergency department.

The large number who came in very quickly taxed the system, Buck said.

Overall, nearly 2,800 emergency department visits for heat illness were logged from June 25 through June 30 in a region that includes Oregon, Washington, Idaho and Alaska, including more than 1,000 on June 28 alone, according to the Centers for Disease Control and Prevention. At least 112 deaths in Washington and 115 deaths in Oregon have been linked to the heat wave, state officials said.

Among the sickest patients St. John saw was a woman in her 70s who arrived at the Harborview ER on June 28 confused and weak, with a core body temperature of 104 degrees. A family member had discovered her ill at home. St. John said a colleague had mentioned the body bag technique just days earlier, so he gave it a try.

The treatment involves filling a body bag with a slurry of water and ice, putting the patient inside and zipping the bag just up to the armpits to allow access for medical equipment and close monitoring. The self-contained bag keeps the ice and water close to the patient’s skin.

Within several minutes of her being placed into the bag, the woman’s temperature dropped to 100.4 degrees, just enough to get her out of that danger zone, St. John said. She was removed from the bag, dried off and placed on a gurney, allowing her body’s natural cooling abilities to take over. After she was admitted to the hospital, she recovered fully, he said.

As the effects of climate change lead to hotter temperatures in more places — including historically temperate zones where air conditioning isn’t in wide use — using body bags to rapidly treat heat illness is a logical solution, said Lipman, who directs Stanford’s Wilderness Medicine Fellowship and runs Global Outdoor Emergency Support, which provides medical guidance for outdoor travelers.

Every hospital has body bags. Every hospital has ice machines, Lipman said.

He and colleagues described the treatment of an 87-year-old woman with cancer who was found unconscious in a parking lot during a heat wave in the San Francisco Bay Area, another region not accustomed to sustained high temperatures. It was July 2019, which was then designated the hottest month recorded on Earth. Using the ice- and water-filled body bags, doctors cooled her temperature from 104 degrees to 101.1 within 10 minutes. She, too, fully recovered.

Immersing patients in cold water has long been the gold standard for treating athletes with heatstroke caused by exertion, Lipman said. It’s the most efficient method because water conducts heat away from the body about 25 times faster than air.

For now, the body bag treatment has been studied mostly in younger, healthier people, and some doctors worry about the effects of cold water on older people and whether the technique might induce shivering that actually raises body temperature. Lipman agrees that further study is needed but said his experience has found that the cooling benefits will outweigh any harm of shivering.

And what about patients who might shudder at the thought of being zipped into body bags?

Because they’re generally so ill when they arrive and get treated so quickly, it’s unlikely they’re aware, Lipman said, adding: But you’d need to ask them.
