The Top Automation Mistakes Killing Facebook Ad Accounts in 2025

Facebook remains one of the most profitable ad platforms in 2025 — but also one of the most unforgiving when it comes to automation mistakes.

We’ve seen too many agencies and solo media buyers lose high-value ad accounts because of avoidable browser automation errors.

Here are the top automation mistakes killing Facebook ad accounts today — and how teams using Multilogin avoid them to scale safely.

1. Running Multiple Ad Accounts in Shared Browser Profiles

This is the #1 mistake. Many teams run multiple Business Managers (BMs) or ad accounts in shared profiles — even within the same browser instance.

Facebook instantly detects shared storage artifacts, resulting in cross-linked bans.

Solution: Use Multilogin to run fully isolated browser profiles — one profile per BM or ad account, with no shared storage.

2. Fingerprint Drift Across Sessions

Cheap browser tools (AdsPower, Dolphin, Incogniton) often introduce fingerprint drift:

• Canvas fingerprint changes subtly
• AudioContext shifts over time
• Fonts enumeration inconsistencies

Facebook detects this as an unnatural device change — triggering manual reviews and bans.

Solution: Multilogin locks fingerprints consistently across sessions and devices.

3. Proxy + Timezone + Locale Mismatch

Running a US proxy with a Vietnam timezone, or a European proxy with a browser in English (US) locale, is a red flag.

Facebook expects perfect alignment between:

• Proxy geolocation
• Browser timezone
• Browser language and locale

Solution: Multilogin automatically aligns these layers for each profile.

4. Using Headless Automation Without Human-Like Behavior

Headless browser automation is easy to detect in 2025. Many bans occur when using pure Playwright or Puppeteer without human-like interaction layers.

Solution: Run Playwright or Puppeteer inside Multilogin profiles — and implement human-like behavior patterns (mouse movement, typing delays, scrolling).

5. Insecure Profile Sync and Team Sharing

Many teams manually move profiles between devices or share login details — corrupting cookies, causing session loss, and triggering device fingerprint mismatches.

Solution: Multilogin offers encrypted profile sync and team role-based access, maintaining session integrity across distributed teams.
