right, need proxies that can actually verify ads across different geos without getting flagged immediately. tried a few residential providers last month and the detection rates were laughable - like 60% blocked within 24 hours. my current setup uses rotating residential with custom headers but even that's getting expensive fast. specifically looking at mobile proxies now since they should mimic real user behavior better for ad platforms, but the pricing i'm seeing is insane. anyone running actual ad verification campaigns right now? what's your monthly spend per geo and what failure rate are you tolerating? bonus points if you've compared static residential vs mobile for this specific use case.
