Let's start with a real scenario.
Xiao Wang runs cross-border e-commerce with three stores in three environments. Proxies and fingerprints are all configured, and he feels good about himself. Until one day, he opens Whoer and casually tests — a big 67%. He freezes: what does this number mean? Did I configure something wrong? Will my accounts disappear someday?
He later learns this number is called the anonymity score (shown as "anonymity level" in Whoer's UI; in English it's the leaks score). It's like an "environment credit score": the higher it is, the more your IP, network, and browser look like an ordinary user to websites; the lower it is, the more you look like "machine operation".
This article explains it thoroughly: what the anonymity score actually is, how it's calculated, why 90% is the safety line, and what to fix when the score won't go up.
In one sentence: the anonymity score is a "safety score" Whoer gives your environment — 0 to 100%, measuring "whether your environment looks like a normal user to websites".
Open whoer.net and the score is usually right in a prominent spot on the homepage. Its official positioning is the "leaks score": it detects whether you leak DNS, WebRTC, or IP when using a proxy or VPN — leaks that expose your real location and identity. Fewer leaks, higher score; more leaks, lower score.
You can think of it as the "overall health index" on a check-up report:
For people running multiple accounts, this score has an even more direct meaning: it's roughly "how platform risk control will view this environment". An account with a low anonymity score is "suspicious network environment" in the platform's eyes — at best it triggers identity verification, at worst a direct ban. So it's not a reference indicator; it's an early-warning indicator.
The anonymity score isn't made up on the fly — it's a weighted result of multiple detection items — mainly four groups: leak detection, proxy detection, timezone/language, and fingerprint consistency.
Let's break down what each group tests:
A vivid example: say the base score is 100; a WebRTC leak exposing your real IP may directly deduct 30-40 points, a timezone mismatch another 10, and the IP being recognized as datacenter another 15 — stack a few items and that's how 67% comes about. What you see as "one score" is actually several detection points losing points at the same time.
Because 90% is the "platform risk-control trust line" — above 90% means the environment has no obvious anomaly signals and the platform will most likely treat you as a normal user; below 90%, each point corresponds to a suspicion risk control can catch.
A common way to band the ranges:
| Range | Meaning | The platform's "attitude" |
|---|---|---|
| 95%-100% | Ultra-clean zone, almost flawless | Treated as a normal user (though long-term 100% is itself rare) |
| 90%-94% | Safe zone, the passing line for multi-account operations | Basically no intervention |
| 80%-89% | Observation zone, 1-2 identifiable issues | May "look twice" |
| 70%-79% | Risk zone, obvious leaks or contradictions | Probability of triggering verification rises noticeably |
| Below 70% | High-risk zone, environment basically "naked" | Must fix before logging into important accounts |
Platform risk control logic is simple: low-score account = abnormal environment = high risk, verify first. New accounts are especially sensitive to this score — new accounts have no trust built up yet, and a low environment score means double "suspicion", multiplying the odds of a ban. Older accounts have some "historical credit" as a cushion, but a persistently low environment score will get them watched too.
So for multi-account operations, 90%+ is the floor, not the goal — you can float between 92% and 96%, but don't let it stay below 80% for long.

If the score won't rise, 90% of the time it's one of these 6 points. Check in order:
Suggested check order: plug leaks first (WebRTC/DNS) → then switch to a clean IP → finally calibrate timezone/language and fingerprint, starting with the highest weight for the fastest results.

Using MasBrowser as an example, the core steps to configure a "90%+" environment:

Configuring once and testing once beats testing ten times without changing the configuration. How the three detection tools work together (Whoer for network, BrowserScan for fingerprints, Pixelscan for overall checks) is fully covered in Fingerprint Detection Tools Guide; here we focus only on Whoer's anonymity score.A high score doesn't guarantee safety, and a low score doesn't guarantee a ban — treat the anonymity score as a "reference frame", not a "verdict".
The right usage: treat the anonymity score as a "check-up report" — when it drops, investigate; when it's stable, keep going; don't stress over single fluctuations.
It looks like it, but a long-term stable 100% is itself suspicious — real users' environments always have "noise" (occasional timezone deviations, plugin changes, etc.). A "clean but with details" 90%-99% is more realistic than a perfect 100%.
Not necessarily, but the risk rises significantly. A low score means the environment has obvious anomaly signals, and platform risk control has very low tolerance for such environments — not "definitely banned", but "much higher odds of being banned". Before logging into important accounts, raise the score first.
Yes, but it requires maintenance. Dynamic proxies cause IP changes, and system updates affect fingerprints — re-test weekly, investigate the corresponding dimension (leaks, IP, timezone/language) when the score drops, and adjust promptly.
Yes, and it can change dramatically. The new proxy's IP type (residential/datacenter), whether the IP has a bad history, and how well it handles DNS all directly affect the score. Always re-test after switching proxies; don't assume.
The most common causes: the proxy itself is bad (datacenter IP, flagged IP), or there are parameters left unmodified in the environment (e.g. only the UI language was changed but the system language was missed). Go through the 6 point-losing items one by one, paying special attention to WebRTC and IP type.
The Whoer anonymity score is the "health score" of your account environment — it doesn't guarantee you won't be banned, but it lets you know before logging in whether you look "suspicious" in the platform's eyes. 90%+ is the operational floor; when the score won't rise, investigate in the order "plug leaks → switch IP → calibrate timezone/language".
Making "test the anonymity score" a fixed step after every configuration saves far more hassle than finding out the reason after a ban. The free plan already includes 2 environment slots; download MasBrowser, configure the first environment, open Whoer and test once — the moment you see 90%+, you'll have an intuitive feel for what "a clean environment" means.
