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<\/strong>: if a website can still identify you as the same visitor, no amount of proxies will solve the problem.<\/p>\n\n\n\n

1. Why Traditional Crawlers Get Blocked: The Core Lies in Browser Fingerprints<\/strong><\/p>\n\n\n\n

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.<\/p>\n\n\n\n

Reason for Block<\/strong><\/td>Description<\/strong><\/td><\/tr><\/thead>
Same IP \u2260 Different Identity<\/td>Changing IPs while keeping the same browser fingerprint still counts as the same user<\/td><\/tr>
High Fingerprint Consistency<\/td>Identical UA, Canvas, WebGL, etc., detected as automated programs<\/td><\/tr>
Cookie Tracking<\/td>Repeated visits leave traces that trigger risk control mechanisms<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Websites no longer just check the request source\u2014they detect the entire browser identity (Browser Identity)<\/strong>.<\/p>\n\n\n\n

2. VMLogin: Providing a \u201cReal User-Level\u201d Access Environment<\/strong><\/p>\n\n\n\n

VMLogin<\/mark><\/a><\/strong><\/strong><\/strong> is a multi-login fingerprint browser<\/strong> that simulates real user devices by modifying browser fingerprints, creating independent identities for each task, and bypassing anti-bot measures from the root.<\/p>\n\n\n\n

VMLogin Capabilities<\/strong><\/td>Data Collection Advantages<\/strong><\/td><\/tr><\/thead>
\ud83c\udf00 Independent Browser Fingerprints<\/td>Each configuration = one independent user<\/td><\/tr>
\ud83c\udf0d Independent Proxy Settings<\/td>Switch between different countries\/regions<\/td><\/tr>
\ud83e\uddea Automation Compatible<\/td>Works with Selenium \/ Puppeteer<\/td><\/tr>
\ud83d\uddc2 Cookie Isolation<\/td>Tasks remain fully separated<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

This means you\u2019re no longer just sending requests\u2014you\u2019re browsing like a real visitor<\/strong>.<\/p>\n\n\n\n
