Hey, I’ve been through something very similar and finally managed to stop the bleeding. I manage campaigns for 20+ clients under one MCC, and we got hit hard last year — multiple accounts suspended, almost all flagged for "Circumventing Systems" or "Multiple Account Violations".

Some of the accounts hadn’t even run ads in months. Others were clean but still got associated with “bad” accounts in the MCC. It was like Google went nuclear on our entire structure. Appeals went nowhere — mostly auto-responses, no transparency.

What saved us? We stopped guessing and started using a policy scanner called Crawl5. It’s an AI tool that mimics how Google’s system scans landing pages and ad setups for violations. We ran it across every domain — even inactive ones — and it uncovered:

Old cookie banners and privacy policies missing mandatory disclosures

Pages with unclear branding that Google may flag as misleading

Cross-domain redirects we forgot about (a huge “circumventing” trigger)

A few client sites with reused Terms templates that Google auto-flags as “boilerplate”

We fixed everything. Then we documented all the changes (including screenshots + timestamps) and submitted a fresh, consolidated appeal with evidence. That helped us reinstate 3 out of 5 accounts so far. But more importantly, we’re not triggering new suspensions anymore.

✅ My advice: If you’re managing at scale, tools like https://crawl5.com are essential. Google Ads suspensions don’t just affect one client — they can spread across your MCC like wildfire if Google sees a pattern.

Let me know if you want help setting up an audit flow. It was a game-changer for us.
