Why Are IP Proxies So Critical? Social media platforms (such as Facebook, Twitter, Instagram, TikTok) use various methods to detect multi-account operations, with the IP address being one of the core fingerprints. Avoiding Account Association: If multiple accounts are consistently logged into and operated from the same IP address, the platform will likely determine that these accounts belong to the same individual or team. If one account violates the rules, all associated accounts may be banned collectively. Simulating Real Users: The IP addresses of real users typically come from residential IPs in specific geographic locations. Using datacenter IPs or frequently switching IPs will be flagged as suspicious behavior by the platform. Bypassing Geo-Restrictions: Certain marketing activities or content may require IPs from specific regions to be effective. How to Set Up Correctly? Step 1: Choose the Right Proxy Type Residential Proxy IPs come from real ISPs (e.g., Comcast, BT), are the hardest to detect, and have the highest trust level. Suitable for long-term operation of core accounts and high-value accounts. 4G/5G Mobile Proxy IPs come from mobile carriers (e.g., Verizon, Vodafone), offering the highest authenticity and are the top choice. Ideal for highest-risk tasks (e.g., advertising accounts, important brand accounts). Datacenter Proxy Fast, cheap, and stable, but easily identified and blocked by platforms. Suitable for data scraping; not recommended for logging into and operating accounts. ISP Proxy Combines the authenticity of residential IPs with the speed and stability of datacenter infrastructure. A hybrid solution that balances both aspects. Step 2: Establish a One-to-One Fixed Relationship Binding one social media account to one fixed IP address is the golden rule of multi-account management. How to achieve this: When purchasing a proxy service, choose a provider that offers static/fixed residential IPs, or purchase an IP port and ensure you always connect through that port. Step 3: Combine with Browser Fingerprint Management The IP address is only one part of the fingerprint. Platforms also detect your browser fingerprint. Even if the IPs are different, if all accounts use the same browser environment, they can still be associated. Solution: Use anti-detect browsers such as Multilogin or AdsPower. These tools can create an independent, isolated browser environment for each social media account. Each environment has its own IP (via proxy settings) and a unique browser fingerprint. This way, from the platform's perspective, each account appears to be a real user from a different location and device.
