How a Crypto Ad Agency Reduced Cross-Linking Bans by 90% With Multilogin
Running ads for crypto and Web3 projects is one of the toughest challenges in 2025. Ad platforms are hyper-aggressive in detecting and banning related accounts — and cross-linking bans can wipe out entire batches overnight.
One crypto ad agency used to lose entire batches every week. After switching to Multilogin and optimizing their browser stack, they reduced cross-linking bans by 90% — while scaling ad spend to $200k/month.
Here’s how they did it — and why Multilogin is now the browser engine of choice for crypto ad teams.
The Challenge: Cross-Linking Kills Crypto Ad Stacks
Platforms like Meta and Google deploy advanced cross-linking detection targeting crypto ad accounts:
- Shared fingerprint elements across accounts
- Proxy + timezone + locale mismatches
- Cross-session fingerprint drift
- Manual profile sync breaking fingerprint stability
- Browser storage leakage across accounts
The agency’s stack before optimization:
- Mobile 4G proxies
- Playwright + Puppeteer automation
- Browser tool: Incogniton
Results:
- 40-50% of new ad accounts cross-linked and banned within 72 hours
- Entire batches wiped out after account review waves
- Significant team time wasted on rebuilding accounts
The Investigation: Browser Layer Was the Weak Link
Detailed analysis showed:
- Fingerprint drift across sessions with Incogniton
- Timezone and locale inconsistencies
- Cross-profile leakage in local storage and cache
- Headless automation artifacts triggering review
Proxies and automation scripts were solid. Browser layer was the root cause.
The Solution: Migrating to Multilogin
The agency migrated their browser stack to Multilogin, implementing:
- Fully isolated browser profiles — one profile per ad account
- Locked fingerprints — stable across sessions and geo-aligned
- Encrypted profile sync — safe team operations across devices
- Integrated Playwright automation inside Multilogin profiles — human-like interaction
- Fingerprint and behavior monitoring — proactive drift detection
The Results: 90% Reduction in Cross-Linking Bans
After optimizing with Multilogin:
- Cross-linking bans reduced by 90%
- Ad account survival rate improved from 50% → 85%+
- Batch consistency improved dramatically
- Manual review triggers dropped by 70%
- Team time on account rebuilding reduced by 80%
The agency’s conclusion:
“We thought proxies and content were the keys — but fixing our browser layer with Multilogin made the biggest impact on ad stack survival.” — Crypto Ad Agency CEO

Final Thoughts
Crypto ad automation in 2025 is a high-risk, high-reward game. Cross-linking bans can destroy entire ad stacks — unless your browser layer is bulletproof.
Fingerprint stability, profile isolation, and geo-alignment are mandatory to survive.
That’s why top crypto ad agencies are moving to Multilogin — the browser engine built to protect ad stacks and eliminate cross-linking risks in the most challenging verticals.
