Multi-accounting — running several accounts on the same platform — is the foundation of SMM, media buying, and trading on Avito and marketplaces. The main pain point here is always the same: bans. Platforms are good at linking accounts together and blocking them in batches. Let's break down why this happens and how proxies, paired with an anti-detect browser, protect your profiles.
How platforms detect multi-accounts
Anti-fraud systems link accounts using a combination of signals:
- IP address — the most obvious signal. Ten accounts from one IP = one owner.
- Browser fingerprint — Canvas, WebGL, fonts, User-Agent, screen resolution.
- Cookies and LocalStorage — traces of previous sessions.
- WebRTC/DNS leaks — they expose your real address past the proxy.
- Behavior — identical action patterns and activity times.
The golden rule: one account, one IP
For sensitive platforms (social networks, Avito, ad accounts) you assign a single proxy to each account. Rough guidelines for the load per IP:
| Platform | Accounts per IP |
|---|---|
| Avito | 1–2 (1 is better) |
| Instagram* / social networks | 1–3 |
| Facebook* Ads / media buying | 1 |
| Marketplaces (seller account) | 1 static IP |
* Instagram and Facebook belong to Meta, which is recognized as an extremist organization in Russia.
The stack for safe multi-accounting
- An anti-detect browser — a unique fingerprint for every profile. See our guide to anti-detect browsers.
- A separate proxy per account — preferably a mobile or residential IP with high trust.
- Consistent geo, language, and time zone — everything must match the country of the IP.
- Clean cookies — each profile keeps its own history.
Static IP or rotation
For logging in and any important actions the IP must be stable — a sudden address change in the middle of a session is suspicious in itself. Rotation is reserved for background tasks: scraping, browsing feeds, collecting data. For the details, see our article "What are mobile proxies".
Case study: 5 Avito accounts
A seller created 5 Avito accounts and ran them all through a single home IP and an ordinary browser. Within a day all five were banned — the platform linked them by IP and fingerprint. The setup that works: 5 anti-detect profiles + 5 mobile IPs (one per account) with a static session at login. The accounts stay alive and their activity never overlaps. Ready-made options are on our proxies for Avito page.
FAQ
How many accounts can I run from one IP?
On strict platforms — 1, at most 2–3. The more valuable the accounts, the stricter the "one IP, one account" rule becomes.
Is a proxy alone enough, without an anti-detect browser?
No. A proxy hides your IP, but the accounts will still be linked by the browser fingerprint. You need the proxy + anti-detect combination.
Why do accounts get banned even with a proxy?
Common reasons: a cheap server IP, WebRTC/DNS leaks, a mismatch between geo and time zone, or one proxy shared across many profiles. Test your setup with our checker.
Which proxies should I choose?
Mobile or residential proxies with high trust. Pick one in the PROXYLEET catalog or in the mobile proxies for Russia section.
