Multi-account isolation with Static Proxies

For store operations and multi-account social work, isolation is the core of account safety.

This page covers how platforms link accounts, and why you need an independent browser profile plus Static Proxies to keep environments apart.

1. How platforms link accounts

Risk systems usually compare:

1. Network (IP location and history):
   • Several accounts log in from the same public exit IP in a short window;
   • Shared, flagged, or heavily reused datacenter IPs;
2. Device fingerprint (hardware):
   • Matching Canvas hash, WebGL, AudioContext, screen size, and font list;
3. Cookies and storage:
   • Cookies or LocalStorage leaking across profiles.

2. Why rotating IPs are a poor fit for long-lived accounts

Rotating Proxies (new IP per request or a short sticky window) work well for crawlers. They do not work well for a long-lived shop or main account:

• A real person or office usually stays in one city. Large IP jumps trigger security checks;
• Shared rotating pools do not guarantee a dedicated IP over time.

3. What Static Proxies do

1. Dedicated for the plan period: that line and exit IP are yours; nobody else shares them;
2. ISP-grade reputation: exits come from real broadband or commercial lines with reputable ASN;
3. Stable Entry Point, optional refresh: hostname and port stay the same. If you need a new exit IP, you can request one without rebuilding the client config.

4. Standard isolation layout

• Software: one antidetect / fingerprint browser profile per account (separate cookies and hardware fingerprint);
• Network: bind each profile to its own JoyProxy Static Proxies line;
• Result: accounts are isolated on both exit IP and device fingerprint.
