Had the same issue a while back — lost a few accounts fast running essay-related offers. Google doesn’t play with that niche anymore. What finally worked for me was using a solid cloaker. I tried a few cloakers like Noipfraud which was easy to setup but didn’t hold up long. Then i shifted to Keitaro + scripts which was flexible but needs constant customization. Then i switched to TrafficShield, which works best for me, solid filtering, real-time protection, and kept my campaigns live way longer.
Though nothing is ever bulletproof, but a good cloaker can be the difference between burning accounts weekly and actually scaling. If you’re serious about pushing on Google, investing in a proper setup is worth it.
