Those money-laundering and scam-enabling services, however, are far from the only shady offerings found on Xinbi Guarantee’s market. Elliptic also found listings for surrogate mothers and egg donors, with one post showing faceless pictures of the donor’s body. Other accounts have offered services that will, for a payment in Tether, place a funeral wreath at a target’s door, deface their home with graffiti, post damaging statements around their home, have someone verbally threaten them, throw feces at them, or even, most bizarrely, surround their home with AIDS patients. One posting suggested these AIDS patients would carry “case reports and needles for intimidation.”
Other listings have offered sex workers as young as 18 years old, noting the specific sex acts that are allowed and forbidden. Elliptic says that one of its researchers was even offered a 14-year-old by a Xinbi Guarantee merchant. (The account holder noted, however, that no transaction for sex with someone below the age of 18 would be guaranteed by Xinbi. The legal age of consent in China is 14.)
Exactly why Xinbi Guarantee is legally registered in the US remains a mystery. Its incorporation record on the Colorado Secretary of State’s website shows an address at an office park in the city of Aurora that has no external Xinbi branding. The company appears to have been registered there in August of 2022 by someone named “Mohd Shahrulnizam Bin Abd Manap.” (WIRED connected that name with several people in Malaysia but couldn’t determine which one might be Xinbi Guarantee’s registrant.) The listing is currently marked as “delinquent,” perhaps due to failure to file more recent paperwork to renew it.
For fledgling Chinese companies—legitimate and illegitimate—incorporating in the US is an increasingly common tactic for “projecting legitimacy,” says Jacob Sims, a visiting fellow at Harvard’s Asia Center who focuses on transnational Chinese crime. “If you have a US presence, you can also open US bank accounts,” Sims says. “You could potentially hire staff in the US. You could in theory have more formalized connections to US entities.” But he notes that the registration’s delinquent status may mean Xinbi Guarantee tried to make some sort of inroads in the US in the past but gave up.
While Telegram has served as the chief means of communication for the two markets, the stablecoin cryptocurrency Tether has served as their primary means of payment, Elliptic found. And despite Telegram’s new round of removals of their channels and accounts, Xinbi Guarantee and Huione Guarantee are far from the only companies to use Tether and Telegram to create essentially a new, largely Chinese-language darknet: Elliptic is tracking close to 30 similar marketplaces, Robinson says, though he declined to name others in the midst of the company’s investigations.
Just as Telegram shows new signs of cracking down on that sprawling black market, Tether, too, has the ability to disrupt criminal use of its services. Unlike other more decentralized cryptocurrencies such as Bitcoin, Tether can freeze payments when it identifies bad actors. Yet it’s not clear to what degree Tether has taken measures to stop Chinese-language crypto scammers and others on Xinbi Guarantee and Huione Guarantee from using its currency.
