New Proxies in Place, but Accounts Keep Dropping: A Breakdown of Common Mistakes When Working With Proxies

A familiar picture. You bought proxies, set up an antidetect browser, separated your accounts into individual profiles, launched your ad campaigns. And two days later half of your ad accounts are banned, the deposits are gone, and you are sitting over a spreadsheet of expenses again trying to figure out what went wrong. The first thought for almost everyone is the same: the proxies are bad, time to switch providers.

Sometimes that is true. But in nine cases out of ten the problem is not the proxy itself, it is how people work with it. A proxy is not a magic "do not ban me" button. It is a tool, and like any tool it punishes carelessness. The antifraud systems of Meta, Google, and TikTok in 2026 look at much more than just the IP address. They cross-check dozens of parameters, and one mismatch in that chain cancels out everything you spent on expensive residential or mobile proxies.

Mistake #1. Choosing the Wrong Proxy Type for the Task

The most common and most expensive mistake. A beginner sees that datacenter proxies cost several times less than residential and mobile ones, and uses them for everything. For account farming, for warm-up, for launching ads. And then wonders about the bans.

The thing is, each proxy type has its own purpose.

Datacenter proxies are fast and cheap, but their subnets have long been known to antifraud systems. They work well for tasks where anonymity is not critical: parsing open data, checking search results, technical tasks. For social networks and ad accounts they are a path to a quick ban.

Residential proxies are real IP addresses of devices registered with internet service providers. This traffic is as close as possible to the behavior of a live user and is far harder to filter automatically. They suit most tasks in affiliate marketing, multi-accounting, working with marketplaces, and geo analytics.

Mobile proxies run on real SIM cards in carrier networks. In mobile networks thousands of subscribers reach the internet through a single external IP, which is standard NAT practice among carriers. Platforms do not ban such addresses by default, otherwise hundreds of ordinary people would fall under the filter. That is why mobile proxies are ideal for account farming and warm-up and for working with the platforms most sensitive to fraud.

A simple rule: the higher the risk of a task, the more "alive" the proxy should be. For running ads and warm-up, do not save on the type.

Mistake #2. Saving on Pool Quality and Taking Dirty IPs

The price of a proxy is made up not only of the type but also of the quality of the address pool. Cheap offers often mean you are buying IPs that dozens of people before you already used for spam, scraping, and gray schemes. Such an address comes to you already carrying a bad reputation.

Antifraud sees the history of an IP. If spam was recently sent from that address, or accounts were registered there in bulk, your new profile falls under suspicion before its very first action. You seem to be doing everything right, but the start is already a losing one.

How to protect yourself. Look for providers that offer clean pools and do not resell the same addresses to an endless number of clients. A good sign is when the system itself rotates active addresses, removes unused ones, and eliminates duplicates, while the IPs themselves are collected legally. Check a fresh address through fraud-scoring services before you place a valuable account on it. It takes a minute and saves your budget.

Mistake #3. Ignoring Geo Consistency

This is a classic that even experienced players get burned on. The account is registered for one country, the proxy gives an IP of another country, and the ads run to a third geo. For antifraud this is a clear signal that something is off.

The platform logic is simple. A real person from Germany logs in from a German IP, has German as the system language, and runs ads mostly to their own region or neighboring ones. But if the account is "German," logs in from a Philippine IP, and targets Brazil, the system sees the mismatch.

The rule here is strict: the geo of the IP, the geo of the account, and the logic of your targeting must be consistent. If you work in a specific country, take proxies of that country and keep the profile in the same geolocation stably, rather than jumping across addresses every day. A good provider lets you select the geo down to the city and carrier, and that is worth using.

Mistake #4. Forgetting About Time Zone and System Language

You matched the geo of the IP, but forgot about the rest of the digital environment. This is the second half of the same problem, and it catches a great many people.

If your IP shows Spain, but the system is set to Russian, the time zone is Moscow, and activity goes on at night by Spanish time, antifraud folds these small details into one overall picture. Each detail on its own is insignificant, but together they reveal that behind the "Spanish user" sits someone from a completely different place.

What to synchronize. The time zone in the antidetect browser to match the proxy geo. The system language and browser language to match the region. The time of your activity at least roughly within the working hours of the target country. The antidetect browser covers most of these parameters, but the "proxy plus profile" combination needs to be checked manually rather than relying on default settings.

Mistake #5. Handling Rotation Incorrectly

People get this wrong in both directions.

Some set rotation too frequently where it does harm. The account constantly changes its IP, and to the platform this looks as if the user is teleporting across cities. For stable work with a single account you need sticky session mode, where the same IP stays attached to the profile for the whole session.

Others, on the contrary, sit on a static datacenter address where mobile rotation is needed. For example, in mass account farming it makes more sense to use mobile proxies with the natural change of the carrier IP. Residential proxies, meanwhile, offer flexible rotation to choose from: on request, by timer every 5 to 20 minutes, or in sticky session mode for long sessions. The main thing is to match the mode to the scenario.

The rule is simple. One valuable account is one stable IP in sticky session mode. Mass operations and farming are mobile proxies with managed rotation. Do not mix the scenarios.

Mistake #6. Running Several Accounts Through One IP

A very common mistake at the start, especially when you want to save money. A person buys one proxy and runs three, five, ten accounts through it. The logic of "well, it is a clean residential IP" does not work here.

As soon as a batch of accounts logs in from one address, antifraud links them into a single cluster. Then the domino principle kicks in: one account gets banned, and all the others that sat on that IP fall under suspicion after it. You lose not one profile but the whole bundle at once.

The rule is firm: one account is one separate IP. Yes, it is more expensive. But losing ten warmed-up accounts along with the deposits poured into them costs incomparably more than a reasonable number of proxies from the very beginning.

Mistake #7. Starting Without Warm-Up

The final mistake, which undoes everything else. Suppose you did everything right: the correct proxy type, a clean IP, consistent geo, a separate address for the account. And then you register the ad account and on the very same day pour the maximum budget into an aggressive offer.

For the platform this looks unnatural. A real person does not behave this way. A new account that immediately starts spending large sums is a textbook signal for antifraud.

Warm-up is the period when the account behaves like a live user: scrolls the feed, joins groups, leaves reactions, gradually builds up activity. And the whole time it must sit on the same stable IP in sticky session mode. If you change the address or geo in the middle of warm-up, all the work is reset to zero. That is exactly why the combination of "a quality proxy plus patient warm-up" matters more than the choice of a specific offer.

A Short Checklist Before Launch

So you do not have to keep everything in your head, run through this list before setting up a valuable account:

• The proxy type is chosen for the task. For farming and running ads, mobile or residential, not datacenter.
• The IP is checked for cleanliness and fraud-scoring before the account logged in on it.
• The geo of the IP, the geo of the account, and the targeting logic are consistent with each other.
• The time zone, system language, and activity time are synchronized with the geo.
• The rotation mode matches the scenario: sticky session for a single account, mobile rotation for mass tasks.
• One account sits on one separate IP, without crowding.
• Warm-up was completed on a stable address, without sharp geo changes.

A separate word on choosing a provider. Once you have decided on the proxy type, it is important to get it from a service that offers clean pools and stable IPs for the geo you need. Among those that cover both mobile and residential proxies for affiliate marketing and multi-accounting tasks, you can take a look at Prosox, for example. It is convenient that there is a chance to test before buying: at registration you get 250 MB for testing, so you can run the proxies on your own tasks and assess the cleanliness of the pool before putting valuable accounts on them. With the promo code whitelink20 there is a 20 percent discount on your first purchase. The main thing is to look not at the lowest price but at the quality of the pool and the stability of the addresses, because that is what account survivability depends on.

Conclusions

In short, bans despite having proxies are almost always a matter of discipline, not the provider. Proxies give you a clean and suitable IP, but everything else in the chain you build yourself: geo consistency, synchronization of the digital environment, correct rotation, account isolation, and patient warm-up.

A cheap proxy used for the wrong task will burn through your budget faster than the most expensive one will save it. So first figure out your work scenario, and only then choose the tool to fit it. A quality proxy like Prosox removes part of the risk at the IP level, but the final result still depends on how carefully you went through all the points above.

Treat proxies as a foundation, not as insurance. Then accounts will stop dropping, and your budget will start working toward results.
