One month ago, the messaging app Telegram summarily beheaded the online industry of Chinese-language crypto scam services: It banned virtually all accounts related to the first and second most popular marketplaces for vendors offering money laundering, stolen data, and a variety of other illicit wares to the vast criminal enterprises carrying out investment scams from compounds across Southeast Asia. Then, Telegram watched impassively as those black marketeers rebranded, rebuilt, and returned to business as usual on the messaging service's platform. On Monday, crypto tracing firm Elliptic published a new report showing how the industry of Telegram-based Chinese-language black markets for crypto scammers has bounced back in the wake of Telegram's takedown last month of the two biggest of those bazaars, known as Haowang Guarantee and Xinbi Guarantee. Before Telegram banned the two markets' channels and usernames on May 13, they had together enabled a staggering $35 billion in transactions, much of which represented money laundering by crypto scam operations that steal billions from Western victims and force tens of thousands of people to carry out scams in forced labor compounds across Cambodia, Myanmar and Laos. Since Telegram's purge, however, Elliptic has found that other smaller markets have now grown to almost entirely fill the vacuum those two key marketplaces left behind—and Telegram appears to have no plans to stop them. In particular, one market called Tudou Guarantee, partially owned by Huione Group, the same parent company as the now-defunct Haowang Guarantee, has more than doubled in size, likely taking in many of the scammer-friendly services displaced by Telegram's bans and again enabling those fraudsters' billions of dollars a year in illicit revenue. Its main channel now has 289,000 users by Elliptic's count, close to the 296,000 users that Haowang Guarantee had at its peak. Xinbi Guarantee, too, has relaunched on new channels and regained hundreds of thousands of users, Elliptic says. In terms of sales, Tudou is now enabling around $15 million a day in crypto payments, close to the $16.4 million Haowang was facilitating daily, according to Elliptic. “Telegram recognized this was illicit activity and the kind they didn't want to be hosting, and so they deleted the channels and banned the associated usernames. But it was clear that these people wouldn't just give up, that they would transfer to different marketplaces,” says Tom Robinson, Elliptic's cofounder. “These scammers have inflicted misery on millions of victims around the world, stealing billions of dollars. Unless these marketplaces are actively pursued, they will continue to flourish.” Posts Elliptic shared with WIRED from Tudou Guarantee—now by some measures the biggest black market on the internet—show examples of money laundering services, offers of scam website development, and vendors selling stolen personal data that scammers use for targeting. Another Tudou post explicitly offers prostitution, including references to possible minors: “Students, queens, lolita,” the post states next to pictures of young women. “All available!!” WIRED reached out to Tudou Guarantee for comment via an administrator's Telegram account but didn't receive a response.
