FAQ on proxy for arbitration: ban by IP and «cleanliness»
Today, many affiliate marketers rely on mobile proxies to avoid account bans. However, beginners often wonder: why use mobile proxies, what are mobile proxies, and how mobile proxies differ from regular proxies? In this article, you'll find answers to frequently asked questions and learn what mobile proxies are best used for in 2025.
Why Facebook Bans Immediately After Logging in From a New IP
The main reason Facebook blocks an account after logging in from a new IP is suspicious activity. Meta flags sudden IP changes as potential hacking attempts or fake registrations. Common mistakes include:
- Using public free proxies.
- Frequent IP changes (especially if Facebook blocks accounts during registration).
- Connecting through blacklisted IPs or VPNs.
If you receive a notification saying "Facebook: your account has been blocked," switch to verified mobile proxies that have passed cleanliness and anti-fraud checks.
Speed Test and Proxy "Cleanliness": What to Check
To select clean mobile proxies, pay attention to three main parameters:
- Speed Test: fast mobile proxies ensure stable content loading, minimizing the risk of account freezes.
- IP reputation: use IP-score services to verify there are no blacklist entries or suspicious tags.
- Connection stability: even the best free proxy servers may lose IP connections, causing issues like "mobile proxy freezes".
Always test mobile proxies using specialized services to reduce the chance of account bans.
Multi-Ports and How Many Threads a 4G SIM Can Handle
When choosing a multi-port mobile proxy, remember the number of simultaneous connections (threads) depends on the hardware and the SIM card plan:
- A regular 4G SIM can reliably handle 5–15 threads.
- Professional solutions (LTE routers) allow for 30–50 simultaneous threads.
- If you are looking for mobile 4G proxies for any purpose, confirm limits with your provider. Standard solutions for arbitrage typically support around 20–25 stable threads per SIM card.
Multi-port proxies significantly save budgets, but it's crucial not to overload a single IP to maintain connection quality.
Unlimited Proxies: Are 1000 Advertising Threads Realistic?
Market promises like "unlimited mobile proxies" and "proxies with on-demand rotation" are common. However, realistically:
- Rotating proxies do offer high throughput thanks to regular IP rotation.
- Even the best mobile rotating proxies have physical limitations. Typically, stable performance is possible for 100–150 threads per IP pool.
- For 1000 threads, you'll need at least 10–15 separate IP pools or specialized services that rotate multiple SIM cards automatically.
Be cautious of providers promising thousands of simultaneous threads from one device—technically, this isn't feasible without compromising quality and increasing ban risks.
Conclusion: A strategic approach to selecting mobile proxies and understanding the reasons behind account bans will allow you to run effective Facebook Ads campaigns. Always choose reputable proxy services, regularly test IP cleanliness, and select realistic solutions for thread counts and IP rotations.
