The profile was working fine, but after changing or binding the proxy, the account got banned within just a couple of hours — a familiar situation for arbitrage specialists and SMM professionals. The problem is almost always not with the anti-detect browser itself, but with how the proxy is bound to the profile. We analyze specific mistakes in AdsPower and Dolphin Anty that lead to platforms detecting multi-accounting and show how to set up the connection correctly.
Why the Proxy, Not the Browser, Breaks the Profile
Anti-detect browsers Dolphin Anty and AdsPower mask the device fingerprint: canvas, WebGL, fonts, timezone, system language. But all this work is undermined by one incorrectly configured parameter — the proxy. Facebook Ads, TikTok Ads, Instagram, and other platforms build a risk profile not only based on the fingerprint but on a combination of signals: IP address, geolocation, timezone, connection type, and session behavior over time. If the proxy does not align with these parameters, the system detects a desynchronization and flags the account as suspicious.
For example, if the profile is set to the New York timezone, but the proxy connects through a data center in Germany — this is a direct signal for the anti-fraud system. Or if the proxy's IP address is already blacklisted due to previous usage by hundreds of other accounts — then a ban can occur even without errors in the fingerprint. This is why most "unexplained" bans are actually explained by one or two mistakes in proxy configuration.
Proxy Binding Errors in AdsPower
AdsPower is one of the most popular anti-detect browsers among arbitrage specialists due to its flexible proxy management and mass profile import. However, this flexibility creates room for errors during setup.
1. Importing Proxies Without Checking Geolocation
Mass importing a list of proxies via CSV is convenient, but AdsPower does not always automatically pull the exact geolocation of the IP. As a result, the profile may show the timezone of Moscow, while the proxy is physically located in the Netherlands. Before launching a campaign, always check the "Proxy Detection" tab in the profile settings — it displays the actual country and city of the IP address.
2. Using One Proxy for Multiple Profiles
A common mistake among beginners is saving on proxies and binding one IP to 5-10 profiles simultaneously. Facebook and TikTok see several different fingerprints accessing from one address and group them into one risk group. Once one account is banned, all others linked to that same IP fall under a chain ban.
3. Incorrect Proxy Type Selection in Settings
In AdsPower, when adding a proxy, you need to specify the protocol accurately: HTTP, HTTPS, SOCKS5, or SSH. If the actual proxy operates on SOCKS5, but HTTP is selected in the settings, the connection may be unstable or may not mask the real user's IP in certain scenarios. Always check the protocol with the proxy provider and match it with the settings in the profile card.
4. No Permanent Proxy Binding to a Specific Profile
If the proxy changes from session to session for the same account, the platform detects sharp jumps in geolocation. Even a residential IP won't help if today the login was from Warsaw, and in an hour — from Prague. For long-lasting accounts in AdsPower, you need to bind the same static or sticky IP to a specific profile for the entire duration of its existence.
Proxy Binding Errors in Dolphin Anty
Dolphin Anty is actively used by SMM specialists and agencies to manage dozens of Instagram and TikTok accounts for clients. The logic of errors here is similar to AdsPower, but there are nuances in the interface and API.
1. Incorrect Timezone Synchronization with Proxy
Dolphin Anty has a function for automatic timezone detection based on the proxy IP, but it does not always work correctly when using the API or during mass profile creation. It is recommended to manually check the "Timezone" parameter in each profile and match it with the actual location of the IP address before the first launch.
2. Using Data Center Proxies Where Residential IPs Are Needed
Many try to save money by connecting cheap data center proxies for managing Instagram and TikTok accounts. These platforms aggressively filter IP ranges from data centers because regular users access them via home or mobile internet. For social networks and ad accounts, it's better to use residential proxies — they appear as regular home traffic and are less likely to raise suspicion with security systems.
3. Proxy Authorization Errors (login:password vs IP whitelist)
In Dolphin Anty, when adding a proxy, you need to specify the authorization method. If the proxy provider has set up authorization by IP (whitelist), but the profile has a username and password entered — the connection may drop the session in the middle of work, causing Instagram to see a disconnection and a re-login from a "new" device, which also increases the risk of a ban.
4. Checking Proxy Through the Built-in Checker Without a Real Session
The built-in proxy check in the anti-detect browser only shows the connection status and basic geolocation. It does not reveal whether the IP is in the blacklists of a specific platform. A proxy may "pass" the internal check of Dolphin, but still be blocked at the level of Facebook or TikTok due to previous usage by spammers.
5. Working with Shared Proxies in High-Risk Niches
Shared proxies, where one IP is used simultaneously by dozens of different clients of the provider, are a common cause of instant bans when working with ad accounts. For high-risk tasks (Facebook Ads, TikTok Ads), it is advisable to consider dedicated or mobile IPs — they are tied to a specific operator and appear as natural as possible to anti-fraud systems.
Which Type of Proxy to Choose for the Task
Proxy binding errors often begin even before opening the anti-detect browser — at the stage of selecting the type of proxy. Below is a table with recommendations based on tasks.
| Type of Proxy | Suitable for | Ban Risk |
|---|---|---|
| Residential Proxies | Instagram, TikTok, Facebook Ads, long-lasting accounts | Low |
| Mobile Proxies | Facebook Ads, TikTok Ads, high-risk arbitrage | Very Low |
| Data Center Proxies | Scraping marketplaces, tasks without strict anti-fraud | Medium-High (for social networks) |
For farming and managing ad accounts, data center proxies almost always lose — their IP ranges are known to platforms and are often already on lists of suspicious addresses. Residential and mobile IPs are more expensive, but they allow a profile in AdsPower or Dolphin Anty to last weeks and months instead of just a few hours.
Checklist for Proper Proxy Binding
Before launching any profile in the anti-detect browser, go through this list — it will take 5 minutes but will save you from losing your account.
- Checked the country and city of the IP through a geolocation service, not just through the browser's built-in checker
- The profile's timezone matches the actual timezone of the proxy's IP address
- The system language and regional settings correspond to the country of the proxy
- The correct protocol (HTTP/HTTPS/SOCKS5) is specified in the profile settings
- The authorization method (login:password or IP whitelist) matches the settings of the proxy provider
- One proxy is bound to one profile, with no overlaps between accounts
- For ad accounts and social networks, residential or mobile IPs are chosen, not data center ones
- The proxy is not listed in public blacklists (checked via external IP checking services)
IP Rotation and Its Impact on Account Lifespan
Proxy rotation is another common point of errors. If the provider is set to automatically change the IP every few minutes (a standard scheme for scraping), and the profile is used for managing an Instagram account or Facebook ad account, the platform detects constant jumps in geolocation within a single session. For anti-detect browsers, it's important to use sticky sessions — a mode where the IP is bound to the profile for an extended period (from several hours to several days), rather than changing with each request.
In AdsPower and Dolphin Anty, when adding a proxy, there is usually an option to specify a sticky port or fixed session with the provider. Check with the proxy provider whether sticky mode is supported and for how long — for account farming, it is optimal to keep one IP for at least 24-72 hours, gradually changing it only during planned rotations, not chaotically.
How to Test Proxies Before Launching the Profile
Even a quality proxy needs to be tested before binding it to a working profile, especially if the account is already warmed up and has value. The steps are simple:
- Add the proxy to a test profile in AdsPower or Dolphin Anty, not linked to real accounts
- Check the IP through an external geolocation service and ensure that the country and city match the expected ones
- Open a site to check for WebRTC and DNS leaks to ensure that the real IP is not leaking
- Check the speed and stability of the connection — delays over 1-2 seconds are critical for ad accounts
- Only after successful testing bind the proxy to the live profile with the account
Such a test run takes 10-15 minutes but saves hours of work warming up the account, which could otherwise be lost due to a simple technical failure in the proxy settings.
Conclusion
Most "random" bans of profiles in AdsPower and Dolphin Anty are actually explained by specific and recurring mistakes: desynchronization of timezone and geolocation, using shared or data center proxies where a residential IP is needed, lack of sticky sessions, and incorrect authorization. By addressing these points from the checklist above, you will significantly increase the lifespan of accounts and reduce the number of chain bans.
If you manage Facebook Ads or TikTok Ads accounts, pay attention to mobile proxies — they provide the most natural traffic profile and are less likely to be caught by anti-fraud filters. For farming Instagram accounts and long-term SMM promotion, residential proxies with sticky session support are well-suited, while for scraping and monitoring marketplaces, where anti-fraud is not as strict, more budget-friendly data center proxies can be considered.
