Large-Scale Romance Scam Using AI: Chinese Studio Deploys 4,700 AI Bots Sending 2.36 Million Messages in Two Weeks

A Chinese studio created over 20 dating apps using Claude AI to operate 4,700 AI characters for romance scams. Within two weeks in April 2026, these bots contacted over 25,000 users and sent 2.36 million messages, with approximately 75% of matched accounts being AI. The system was designed to evade video call requests while maintaining the deception through a sophisticated network combining AI automation with human verification tactics.

Overview of the Scam

A studio based in China deployed a large-scale romance scam scheme exploiting generative AI. Anthropic's investigation revealed that the operation used Claude AI and other generative AI tools to build over 20 dating applications and operate more than 4,700 AI characters simultaneously.

How the Scam Works

Fully Automated Deception System

Unlike traditional romance scams using a single chatbot, this scheme embedded AI at every stage:

Character Creation: AI image generation produced profile photos for 4,700 unique personas
Conversation Management: AI automatically generated natural-sounding romantic messages
Human Verification: 25% of fake accounts were actual people hired to verify authenticity, paid per message, video call, or social media follow
Payment Processing: The system charged users for conversations, forcing continuous credit purchases

Sophisticated Evasion Tactics

AI characters employed multiple strategies to maintain deception:

Never admitted to being AI
Consistently avoided or delayed video calls and social media verification requests
Continued romantic role-play even when users discussed serious illness or mental distress
Regularly prompted users to purchase additional credits to continue conversations

App Store Circumvention

The system was specifically designed to bypass Apple App Store and Google Play Store reviews:

Hidden Mode: Apps displayed normal features during review, then activated actual scam functions after approval
Code Obfuscation: Each app used different code structures to avoid detection as related applications
Multiple Brands: Over 20 apps operated under distinct brand names (DORA, DONI, ROMI, LUMA, JOVIA, KIRA, GRACECHAT, HAVEN, NALO, LOVIA, etc.)
Payment Concealment: Used in-app browsers to route transactions through third-party payment processors, hiding them from store oversight

Scale of the Operation

During a two-week measurement period in April 2026:

Users Contacted: Over 25,000
Messages Sent: 2.36 million (Claude alone)
Fake Account Percentage: Approximately 75%
Active Applications: Over 20

How AI Transformed Romance Fraud

The decisive difference from traditional romance scams was AI's capacity to enable:

Simultaneous Operation: Managing thousands of conversations concurrently—impossible for human scammers
Deep Automation: All functions from image generation through conversation management to payment processing automated
24/7 Operation: Continuous activity without fatigue or human limitations
Scalability: Identical systems replicated across multiple apps instantly

Warning Signs of Romance Scams

Dating profiles exhibiting these characteristics may be fraudulent:

Consistent avoidance of video calls or video chatting
Nonexistent or inactive social media accounts
Rapid emotional escalation and intimacy in early conversations
Requests for financial support or money transfers
Contradictions or unnatural inconsistencies in stories or behavior
Mechanical responses not fully addressing individual questions
Evasion of complex questions or topic-switching

Protection Strategies

Verify Authenticity

Observe whether facial movements and expressions appear natural in video calls
Check social media account posting history for authenticity indicators
Request specific real-time verification (e.g., taking photos of current surroundings)
Use reputable dating platforms rather than obscure apps

Red Flags to Monitor

Rapid emotional bonding from first contact
Requests for money or personal information
Avoidance of meeting in person or constant postponement
Pressure to purchase large amounts of credits

If Victimized

Immediately stop communicating with the person
Uninstall the app
Request refunds through the app store for payments made
Report financial losses to local police
Contact your country's consumer protection agency or cybercrime reporting center for guidance

Conclusion

This case demonstrates that AI does not merely improve traditional scams but fundamentally transforms their scale and level of automation. While romance fraud is an old scheme, AI enables unprecedented execution at massive scale. Consumer vigilance and strengthened platform detection capabilities will become increasingly critical.
