In data collection and market analysis, the biggest challenge is not writing scripts, but dealing with increasingly sophisticated anti-bot mechanisms. Even if you frequently change proxy IPs, your requests may still be blocked (403, 302), or accounts may get banned.
The root cause is not the code, but identity recognition: if a website can still identify you as the same visitor, no amount of proxies will solve the problem.
1. Why Traditional Crawlers Get Blocked: The Core Lies in Browser Fingerprints
Many collectors believe that using a proxy pool or changing IPs is enough to bypass restrictions, but modern anti-bot mechanisms go far beyond that.
| Reason for Block | Description |
| Same IP ≠ Different Identity | Changing IPs while keeping the same browser fingerprint still counts as the same user |
| High Fingerprint Consistency | Identical UA, Canvas, WebGL, etc., detected as automated programs |
| Cookie Tracking | Repeated visits leave traces that trigger risk control mechanisms |
Websites no longer just check the request source—they detect the entire browser identity (Browser Identity).
2. VMLogin: Providing a “Real User-Level” Access Environment
VMLogin is a multi-login fingerprint browser that simulates real user devices by modifying browser fingerprints, creating independent identities for each task, and bypassing anti-bot measures from the root.
| VMLogin Capabilities | Data Collection Advantages |
| 🌀 Independent Browser Fingerprints | Each configuration = one independent user |
| 🌍 Independent Proxy Settings | Switch between different countries/regions |
| 🧪 Automation Compatible | Works with Selenium / Puppeteer |
| 🗂 Cookie Isolation | Tasks remain fully separated |
This means you’re no longer just sending requests—you’re browsing like a real visitor.
3. Practical Steps: Building a High-Success Data Collection Environment
① Create Independent Browser Configurations
- Open VMLogin → Click “New Browser Configuration”
- The system automatically generates independent browser fingerprints (User-Agent, Canvas, WebGL, fonts, timezone, etc.)
② Bind Dedicated Proxy IPs
- Configure a separate proxy for each browser instance
- Ensure each configuration uses a different proxy to achieve independent multi-account access
③ Integrate with Automation Scripts (Optional)
- Retrieve connection parameters and embed them into Selenium or Puppeteer
- Run scripts in a real browser environment, not just sending requests
✅ Advantage: Requests are no longer recognized as automated, greatly reducing the risk of blocks or 403 errors.
4. Typical Data Collection Scenarios
| Use Case | Example Platforms |
| E-commerce Price Monitoring | Amazon, eBay, Shopee product data & reviews |
| OTA Travel Monitoring | Booking, Airbnb room & pricing analysis |
| Social Content Scraping | YouTube, Instagram, X (Twitter) sentiment monitoring |
| Market Intelligence Research | Industry site tracking, comment sentiment analysis |
5. Best Practices (Avoid Triggering Anti-Bot Mechanisms)
✔ Use multiple VMLogin configurations to distribute tasks
✔ Control access frequency and simulate real user clicks and dwell time
✔ Retain cookies to improve efficiency (clear selectively depending on project)
✔ Avoid frequently resetting fingerprints to maintain identity consistency
6. Compliance and Technical Boundaries
VMLogin is designed for market research, data analysis, and legal information collection. Users should comply with the target website’s terms of service and local regulations, and must not collect private information, attack systems, or use it for illegal purposes.
🏁 Conclusion: Welcome to the “Real User Simulation Era”
Data collection is no longer just about sending requests—it’s about simulating real identities.
In an era of increasingly strict anti-bot rules, VMLogin solves not just technical challenges, but access authorization.
