The Download: tracking teachers online, and how influencers navigate algorithms

July 15, 2022

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology.

The book ban movement has a chilling new tactic: harassing teachers online

Nancy Vera was awakened suddenly at midnight on July 12 by the sound of a single gunshot, the bullet ricocheting off her home. She looked at a security camera just in time to see a truck speed away.

Vera was shocked but not surprised. The president of the Corpus Christi, Texas, branch of the American Federation of Teachers, she had recently handed out books with LGBTQ characters at a pride event for local students, alongside a drag queen. In response, she’d been called a “groomer” online, a slur commonly used by devotees of the conspiracy theory QAnon, which claims that powerful people and institutions are ensnaring children in sex trafficking rings.

There is a growing push among Christian and conservative groups across the US to get certain books and topics they deem inappropriate for children removed from school libraries and curriculums. Now the fight is turning increasingly ugly, with people targeting individual teachers’ private social media accounts for scrutiny and even harassment.

“This type of rhetoric is going to get people killed,” Vera says.

How aspiring influencers are forced to fight the algorithm

Last summer, a TikTok creator named Ziggi Tyler posted a video calling out a disturbing problem he found in the app’s Creator Marketplace, a tool that matches creators with brands looking to pay for sponsored content. 

Tyler said he was unable to enter phrases like “Black Lives Matter” and “supporting Black excellence” into his Marketplace profile. However, phrases like “white supremacy” and “supporting white excellence” were allowed.

TikTok apologized and blamed an automatic filter. However, these sorts of problems have cropped up and been flagged by creators again and again.

Brooke Erin Duffy, an associate professor at Cornell University, teamed up with graduate student Colten Meisner to interview 30 creators on TikTok, Instagram, Twitch, YouTube, and Twitter around the time Tyler’s video went viral. They wanted to know how creators navigate the algorithms and moderation practices of the platforms they use.

They found that understanding the algorithms and hidden rules that guide each platform is practically a job in itself. Read our interview with Duffy about her research.

The big story

Meet the scientist at the center of the covid lab leak controversy

February 2022

The Wuhan Institute of Virology holds a critical place in the story of the covid-19 pandemic. A leading center for coronavirus research, it was the first facility to isolate the virus, and the first to sequence its genome. One of its labs, led by virologist Shi Zhengli, focuses on coronaviruses that live in bats, and has spent years trying to understand how they may evolve to gain the ability to infect humans. 

Shi’s work has been at the center of controversy. Some have speculated that the live viruses her team cultured in the lab, including—more worryingly—the ones they created by genetic tinkering, could be the source of the pandemic. 

Inflaming the suspicions are concerns over biosafety procedures at the lab, political tensions between China and the US, and a general sense that the Chinese government is not to be trusted. This is Shi’s side of the story. Read the full story.
