Bangladeshi KYC Farms Target Chinese Claude Users: The Reverse Outsourcing Phenomenon

Since October 2024, the author's 3.5-year-old Claude account was banned and two backup accounts triggered KYC (Know Your Customer) verification when attempting to subscribe. After publishing two articles discussing Claude bans and identity verification, the author's WeChat official account backend was flooded with private messages from suspected overseas verification vendors.

The Contractor Messages

Daily messages arrive from vendors offering KYC bypass services. One screenshot shows a vendor named "SHAKIRUJJAMAN" using typical Bangladeshi English spelling patterns ("-ujjaman" suffix, "MD" prefix for Mohammad) and addressing the author as "Sir" — hallmarks of South Asian outsourcing workers. Another vendor boasts a capacity of 500+ verifications per day and claims recent delivery of 2,000+ orders for a "Cloud Link" project.

Analysis of the Cross-Border Verification Industry

The author traces the phenomenon to Anthropic's gradual rollout of identity verification announced in April 2024. In a previous article, the author predicted that blanket verification policies would fail to stop organized evasion while blocking ordinary users, handing profits to intermediaries. Six months later, Bangladeshi contractors are directly soliciting business via WeChat.

These contractors operate a reverse outsourcing model: they lack compute or models but possess two assets Chinese developers lack — national identities from countries on U.S. tech giants' supported-regions lists, and extremely cheap local labor. Villagers or students need no coding skills; they simply present real IDs to a phone camera for liveness checks, turning seconds of biometric compliance into a sellable digital service.

Contractors find targets by searching WeChat for English abbreviations related to KYC/Claude or following shared article cards in peer groups. They do not read Chinese content; they assume high-frequency keywords indicate a channel partner with demand. The workflow is industrialized: frontend negotiation via WeChat, backend piecework paid at a few RMB per order.

Risk Assessment of Third-Party KYC Services

The author warns against purchasing "real-person" Persona verifications or pre-verified accounts:

Device fingerprint concentration: A contractor completing 500 orders/day means hundreds of accounts verified on a few devices within the same network segment. Device fingerprints are linked in risk-control systems; if one account is flagged, the entire batch faces cascading bans.

Identity-behavior mismatch: An account verified with a Bangladeshi ID, bound to a U.S. virtual card, accessed via Japanese or Singapore IPs, and used intensively for Chinese-language Claude Code sessions creates a severe identity/trajectory anomaly. Under Anthropic's H1 2024 ban wave of 11.4 million accounts, such accounts are unlikely to survive.

Author's Solution and Advice

The author successfully passed KYC using a personal Chinese passport; two weeks later the account remains stable. According to discussions on X (formerly Twitter), Anthropic focuses on whether the user is accessing Claude from a supported country, not on nationality. The author advises: ignore unsolicited English private messages on WeChat (replying may trigger platform violation flags), avoid gray-market KYC services on second-hand platforms, and use one's own passport for verification if needed.
