How to Avoid Account Linking in Large-Scale Online Operations

When managing 50, 100, or even more accounts, any small mistake can lead to catastrophic results. In just a few minutes, the platform may link all accounts together and implement bans.

As the number of accounts increases, the issues become more severe. The more accounts there are, the greater the chance of making mistakes. Every month, the platform's detection systems become more robust in monitoring abnormal patterns between accounts.

This guide will explain how to maintain account independence in large-scale operations, clarify which mistakes can lead to account linking, and how to prevent these errors from occurring.

Why and How Platforms Link Related Accounts

Multi-account operations are generally not welcomed by platforms, as they waste resources and may lead to spam. To combat this, platforms use automated systems to scan accounts around the clock to identify connections without manual review.

The process is quite simple. The platform receives information from each account and matches it in a database. Just two or three similar data points are enough for the system to automatically link these accounts.

Once accounts are linked, they are treated as a single account. If one account is banned, all related accounts will also be affected. Even if an appeal is made, the platform will view it as a continued violation, thus failing to resolve the issue effectively.

To prevent violations of multi-account operations, platforms may mistakenly ban innocent accounts. Since the cost of detection errors is low, platforms do not incur additional expenses in this regard.

Common Signals That Trigger Account Linking

Here are some of the most tracked account linking signals by platforms, which are numerous.

This is the biggest factor in account linking. If two or more accounts share the same IP address, the platform will immediately link them. Even a single shared login using the same IP can result in permanent linking of accounts.

The unique information displayed by a browser includes screen resolution, fonts, plugins, and canvas data. If multiple accounts have the same browser fingerprint, the platform will recognize that they are on the same device.

Every phone and computer has a unique identifier. If multiple accounts log in on the same device, a clear link will be formed. These IDs are read by the platform at each login.

When a user logs into account A and then immediately logs into account B, the platform can identify the relationship between these two accounts. Social networks monitor user logins and logouts, and cross-account trends indicate that the same person is behind them.

Using the same email format or the same phone number for verification links can lead to account linking. Even slight differences, such as name123@gmail and name456@gmail, are warning signals.

If multiple accounts use the same credit card or PayPal account, they will be automatically linked. Billing addresses are also important, and the platform will carefully check payment data.
