Hoarding 5-Digit QQ Numbers

Cause

In 1999, Tencent launched OICQ. By 2000, facing a trademark lawsuit from AOL (America Online), the software was officially renamed "QQ". Around this time, QQ's user base began to grow exponentially, yet Tencent was still a struggling startup unable to find a profitable business model and almost sold itself for a mere pittance. To encourage user adoption, registering a QQ account was entirely free, and the system was distributing highly coveted 5-digit and 6-digit identification numbers.

Process

During this wild west era, ordinary users just registered a single account for chatting, while hackers and tech-savvy opportunists saw a massive arbitrage opportunity. Exploiting the fact that QQ's registration system had no captchas and loose restrictions, they wrote simple automated scripts ("registration bots") to bomb Tencent's servers with registration requests day and night, hoarding accounts in bulk. They meticulously filtered for consecutive numbers (e.g., 12345), repeating numbers (e.g., 88888, 66666), or meaningful birthday numbers. To prevent Tencent from reclaiming these accounts under their "inactive account policy," they also had to use automated login tools to keep the accounts active periodically.

Result

As QQ grew to become the undisputed dominant instant messaging software in China and Asia, possessing a short, lucky "premium QQ number" became a major status symbol and virtual luxury item among Chinese netizens. By 2005 and beyond, 5-digit and 6-digit QQ numbers were being traded for astronomical prices on underground markets. A standard 5-digit number could fetch thousands of RMB, while ultra-premium repeating numbers (like 88888) were sold for hundreds of thousands or even over a million RMB. Numbers generated at zero cost by scripts had transformed into literal digital gold.

🚀 Time Traveler's Playbook (How to Exploit This)

• 🎯 Target Acquisition: Early Tencent OICQ (soon to be QQ) accounts, specifically 5-digit or 6-digit numbers with lucky repeating digits (e.g., 88888, 12345).
• 🛠️ Core Operation: Simply register as many accounts as humanly possible while Tencent is still assigning short numbers for free. Write down the passwords securely.
• 💰 Profit & Extraction: Fast forward a decade. As QQ becomes China's largest digital identity, sell these short "vanity" numbers to wealthy business owners for luxury-car prices.
